Yes. Extensions -> Maps -> Mask Map by Atom Selection...
After selecting your model molecule, you will be asked about an Atom
Selection
use (for example)
//A/20-30
to mean residues 20 to 30 (inclusive) in the A chain.
You will want to click the "Invert Masking" checkbutton.
Masked maps often scroll "slowly" so increase (say to 0.5) the r.m.s.d.
step in the Map Properties.
