Salvage radiotherapy in the absence of a PSMA avid target is incredibly common and will typically involve radiation to the prostate bed and the optional addition of the pelvic lymph nodes.

The majority of post-RALP BCR starts with regional spread in the prostate bed and PLNs, hence the validity of this approach. Of course there's no guarantee that there could also be distant spread that's missed, but that's always going to be the case since PSMA PET has a detection threshold, and some PCa is not PSMA avid.
