Based on the description here:

VDW_RADIUS sets the cutoff radius for the van der Waals pair interactions in Å \AA for the DFT-D2, DFT-D3, DFT-ulg, DDsC, and Tkatchenko-Scheffler methods.

So, does DFTD4 have nothing to do with this parameter?

DFTD4 does not read VDW_RADIUS.
Only following tags are read by the library in VASP:
