"My question was about how to do that in BIAB with frozen tracks"

As I said Biab can be made to do this easy enough the same way Reaper is doing it. The tracks section in Reaper are the same source sections Biab uses, Reaper plays these direct from the RealTrack folder, Biab will decompress then load them into RAM. Reaper has not created any wav files or loaded into RAM.
All the wav instructions in a frozen SGU can be transposed by adding or subtracting to the current pitch shift amount thus keeping the same riffs.
Are you looking to shift 1 or 2 semitones or a lot more ?

The same can be done to convert an FX guitar RT to a direct input guitar RT by just changing the path in the frozen SGU, keeping all the same riffs but DI.
The same can be done with stereo RealDrums converting the same sections to Stems.
