Not that I know of, but if you're looking for a preprocessor, use a
preprocessor!

I'd cp nrpe.cfg nrpe.cfg.m4, and edit nrpe.cfg.m4 to include something
like the following:

dnl This is the preprocessor source to nrpe.cfg
dnl Run it through m4 with 'm4 nrpe.cfg.m4' to
dnl generate usable output.

define(`DONT_BLAME_NRPE', `0')

# normal stuff... blah blah blah

dont_blame_nrpe=DONT_BLAME_NRPE

# more stuff... blah blah blah

ifelse(DONT_BLAME_NRPE, 0,
        `command[check_tns]=do_what_i_want',
        `command[check_tns]=do_what_nrpe_allows');


If you're feeling really ambitious, you could even come up with a
makefile:

all: nrpe.cfg

nrpe.cfg: nrpe.cfg.m4
        m4 nrpe.cfg.m4 > nrpe.cfg
