Well, yes, that's what I've done--but then if I want to turn FSD back on I have to stop.
FSD is far superior to Autosteer. I'd rather not have to choose between TACC/Autosteer and FSD for each drive. I have plenty of long drives where I want TACC for some portions and FSD for other portions.
But apparently that's just the way it is now. Disappointing--and I just bought a brand new Model Y with FSD two weeks ago. If I had realized this change was coming I don't know if I would have made the plunge.
Oh well--I should have read the release notes and social media posts about this update more carefully. You can be sure I'll do that in the future! Overall I still love my Tesla, but I am really disappointed by being "forced" into a choice between TACC/Autosteer and FSD.
