Sure.. You have the source code.. ;-)

It should be ok to just comment out the PDEBUG() and printk() calls that
you do not consider useful. This particular one could, however, be
removed from the default build anyway..

This is build time only.. You can remove PDEBUG() messages by defining
PRISM2_NO_DEBUG, e.g, in hostap_config.h. This may also still work from
the command line:
