Hi, I have a 2018 Premium and it does NOT have the shut off button (even so I really love the Buick). I purchased an ~$100 bypass module that fits by the hood latch but have yet to install it as the service manager at my Buick dealer (who does not try and sell me things or look for work) recommended I do not use it as he has recently had a similar product installed in an Enclave that messed up the main computer. In this instance it can void the warranty etc. He had the same with swaps on halogens for LED headlights. So, for me my simple solution is I just drive it in L and move the selector to 6. It shifts the same as in D and I don't have to think about the start/stop and all, seamless as it is, because start/stop does not engage in L.
