It's true that pcs adds equivalent of "op monitor interval=60s"
as an unconditional fallback when defining a new resource.
Other operations are driven solely by explicit values or by
defaults for particular resource, and this can be turned off
via "--no-default-ops" option to pcs.

FWIW, this could be a way to have monitor explicitly deactivated:

    pcs resource create <name> <res> ... op monitor interval=0s
