Not really, no. The whole point of f-strings is keeping the template
and the interpolations together, and the whole point of localization
tools is keeping them apart. I'm not sure why you're getting that
NameError, but the more fundamental problem is still there; you
absolutely have to do the localization on the constant string with the
template markers still in it, and only afterwards do the
interpolation, so you're basically left with what you're already
doing.
It might be possible to do something with an import hook that
translates _f"...." into _("....").format(...) but that would be the
best you'd get.
