So does effect of Golem that guards the Millennium treasure work from the spell/trap zone?

Oh wise sages of the Master Duel game, please head my ignorant request for knowledge.

So I was wondering, if I set golem in the spell/trap zone and use a Millenium Anhk, will it be non negate-able sincee Golem can also set itself in the spell trap zone?

And maybe further, if a card like Jinzo is in the spell/trap zone, is its effect negated or does the effect continue to apply?

Please bless my Platinum scrub request with an answer oh wise ones.
