I got tired of waiting for the $40 start stop module to get in stock, but found another on ebay for $60. The vendor has sold over 20,000 and it is made in Germany which I think will probably be higher quality, comes with wire pins and is shipped DHL.
The install instructions are a little different with this being a universal model. In order to install it, there are three variations, depending on the signal wire voltage with the start/stop when the ignition is on and off.

Variant 1: 12 volts - Key On/ 0 volts - Key Off
Variant 2: 0 volts - Key On / 12 volts - Key Off
Variant 3: < 12 volts (e.g. 5 volts) - Key On / 0 volts when Key Off

I tried to measure the voltage today and the wires to the start stop panel are really small at least 18 gauge or smaller and I couldn't get a proper voltage reading with my multimeter. Does anyone have this information or a wiring diagram to share?

My high school auto mechanics teacher used to say that the worst thing you can do to a car (in terms of wear) is to start it.
However, I am starting to rethink the whole memory module approach, although I am looking at one which I paid $65, sitting on my desk. The area to fit it is really cramped, it will involve splicing into small wires, will probably be a hassle and might give the dealer cause to void future warranty repair items if discovered.
I am not a mechanic, but I used to do a lot of repairs to my cars, as a hobby. Everything on the VW is ridiculously over engineered, (I really want to say stupid). Simple things like swapping out the battery requires special equipment so you won't have to reflash your ECM and doing a simple oil change requires removing splash shields, making simple DIY jobs unnecessarily complicated. Thanks for your post, I will consider it.

Yes, at the time it was experience with engines with pistons that ran on gasoline.

I sent it back to the seller today. I think that KarstGeo is started to get to me....scary!😊

OK, I just received another start-stop device. I connected it and it works but the device is too long and I could not get the AC control panel to fit correctly. I might try to take off the side panels on the center console so that I can see what is going on later (but it's doubtful), Another one for my tool box!
I just received my OBDeleven and will probably modify the voltage before I decide to fool around with taking off panels.
Anyway, I don't recommend buying it.

Just pull the two wires off the battery that feed voltage to the Stop/Start function. I pulled mine when I got the Atlas, and it has not caused any problems yet. Very simple, and can be plugged back in at any time if necessary.

Thanks for your input. I tried this before, but I am interested in more of a long term, custom solution so I can use it or disable it, as I choose. The device works, but the dongle is too big for the space available. Once I figure out how to remove the side panels on the center console and I can see what is going on, I might try to reinstall the device, but only if I can properly free up some space. I don't want to jam it in.

I have the old OBDeleven model. I haven’t coded it yet, but it should work on my 2019 SE w/Tech

Update. I compacted the stop start memory module by making a "s-loop". The AC panel fits much better but it is still a little tight. I might try to zip tie the dongle together to keep it more compact. Now, when I press the button it saves the last action. I have it set to off now. When I start the vehicle the "deactivate light is "off" for a few seconds then goes "on" and I see "start-stop deactivated" in the center display for a few seconds. So far I like the ability to change my preference without having to go to long coding or pulling off wires under the hood. I'm happy with it.

The operating instructions are in Chinese. There is also a "Service Mode" which will revert the start/stop back to original (always on) by holding the start/stop button in for 5 seconds and similarly for 5 seconds to exit the Service mode.

There are no errors with the memory module. Love it!
