Yes, you can. There is a list of MIDI implementation in the manual.
And as almost any parameter can be assigned as a Flexi destination with a vast choice of MIDI CCs as the source, you can control most stuff. See the sections on Flexi Controllers.
I haven’t yet integrated the full NRPN assignments into the manual, which covers all parameters, but those have been made public on Talkbass as a separate file. Partly because it’s extra work and is likely to only be used by a few more experienced users.
