The following 3 options were enough, as you suggested.
Carpet::max_refinement_levels           = 1
Carpet::refinement_factor                   = 1
CarpetRegrid2::num_centres              = 0

After setting these properly, it turned out the crash wasn't due to 
Carpet. It was now due to inappropriate memory allocation by the 
scheduler in my initial data code.

Thanks
