Yes, you can. But check my videos. I added all assitants to main screen to switch them off and then at the next start all defaulted to start/stop. But in the end, I was able to keep start/stop and lane assist on home screen, they stayed permanently. You can also see from videos how long it takes to start everything and that it's not that precise. I press the toggle but it didn't work, so had to press it second time. Now imagine doing it while driving.
Step 1, added all asistants.

Step 2, I restarted car and it took ages to load the home screen and all of them were start/stop.
Step 3, in the end kept two permanently. So, I can switch them on/off while driving.
