Change watch based on CarPlay status?

I’m not even sure if it’s possible as I’m completely shortcut oblivious, but I have 2 watch faces on my Apple Watch (Series 9). I’d love it if there was a way to use 1 watch face when my phone is connected to CarPlay (and keep that watch face after being disconnected for 15 minutes) and the other one for if it’s not. Is there a way to do such a thing?

TLDR: Watch Face 1 displayed when connected to CarPlay. When I disconnect it, keep that watch face for 15 minutes and then switch to Watch Face 2 (unless connected again to CarPlay)
