[MCU] If I blindly/unknowingly fell into Thor's hammer, groped around and grabbed it for stability, could it move (given that I'm not trying to pick it up but that my inertia from my fall might cause me to move while grabbing it)?

It's been shown fairly clearly that MCU Mjolnir will remain stationary and unmoving unless Thor wills it or a worthy wielder picks it up.

In the very first movie for example, Thor just put it on Loki chest - Loki clearly didn't want to wield Mjolnir, he just wanted to get away from it, but it still pressed down on him and didn't move.

There's really no caveats here - if you grab it for any reason and you're unworthy, Mjolnir won't budge.
