Hmm, this can be tricky since your Tab S6 lite will undoubtedly have a different menu structure than my Pixel 7 Pro or Pixel Tablet. When I get back home from work, I could check my Galaxy A32 5G, which is probably more similar to your menu.
For now, are you able to go to your system settings? If so, search for "TalkBack" in the search bar, and see if you can simply toggle that off (which should still keep the Accessibility Menu active). I can do that on my Pixel 7 Pro, at least.
I can also see if
@mustang7757 or
@Laura Knotek can assist, since they're more familiar with Samsung than I am.
