I don't know if Teamviewer or Anydesk support *BSD, but you can always use xpra - though they say "All BSD variants should work, but are not regularly tested." so you might find a couple hiccups maybe.

I've found xpra --shadow to be almost on par with Anydesk on Linux - even passing through an ssh proxy. But obviously that might depend on GPU encoding which might not always be available on BSD.
