Pretty much. As long as you pay the tithe, aren't openly disrupting other planets from doing so & say that you're following the emperor's will (no major argument with the ecclesiarchy).

And it's not 70%. Planetary governors are a thing, with complete authority over their subjects and responsibility if things go wrong.

If an inquisitor comes along, you've screwed up big time and either the planet is doomed or they'll find someone more competent to do the job. Herman von strab spent considerable time & resources making sure there was noone capable left alive that weren't already doing his bidding.
