In general, backports that aren't fixing regressions or documentation
would need release managers approval. There's some leeway for target
maintainers of ports and other subsystems, for example I sometimes
make executive decisions about the C++ runtime libraries when the
backport only affects an isolated part of the library, or is clearly
safe and an obvious improvement. For bigger changes that aren't
regressions but I'd like to backport I still seek RM approval.

I would guess that for RISC-V which is new in 7.1, if you think the
backport is important and it doesn't affect other targets then it
should be OK.

Maybe one of the release managers can confirm that though.
