I love my vibration-free mirrorless MFT cameras for micro photography, especiallly when used in high-resolution mode. But this mode requires absolute stillness. Environmental vibrations ruin it, and flash does not fix that, even in principle. So when environmental vibrations are severe, I miss my bigger-sensor cameras. But those mirrors flapping around shake my specimens in liquid. It isn't terrible, but I'd like to avoid that.
So I taped my mirror in the "up" position with black electric tape. I use Live View to focus, and everything seems to work fine. I still have the darn shutter moving around, but I don't think it vibrates my specimens like the mirror does. I use delayed firing, long shutter speed, and second curtain flash. Seems to work alright.

I think I used a blackened piece of fine piano wire, shaped to spring into place. First try was a matchstick..
In the last camera I dismantled where I can remember the cord, the cord rose up above a pulley it should have been held taught against, when you pushed the mirror up.
The risk was that it would miss the pulley when the mirror was let down again. That could jam the mirror.
