Will My Fallout 4 Break With An Update If I Launch The Instance Through Steam via Mod Manger 2/F4SE?

I play modded fallout 4 on my steam deck but I am concerned that the supposed “next-gen update” will break my game if/when it releases. If I am launching the game via mod manger 2 through steam will the update go through and/or break my game? How could I prevent this if it would? Thanks for the help :)
