what to put down on dirt floor to minimize dust

Not sure if this is the right forum... but my garage has a dirt floor and there's a lot of dust as the dirt out here in WY is very dry and has a lot of bentonite in it. I guess I could just put down straw or hay but I tend to think that would be a fire hazard. I'm willing to spend $300 for a load of pea gravel. Maybe some day I'll call in a cement truck.

This is just a hot take but what about an earthen floor with rammed earth and linseed oil?  I've also heard of paper bag collage finished with oil.  If you are skeptical look it up before you discount it.

you could do a soilcrete floor pretty quick.
assuming its small space, maybe 4-6 bag of cement, maybe more.?
clear the floor, get it level ish, and then put down the bags of the dry cement directly on the dry floor.
get a small earth mixer, roto tiller, any kind of tiller or last resort a pitchfork and some extra hours and till the dry cement into the top layers of the dirt. wet it lightly as you go, towards the end, then wet it well...come back a bit later and smooth it out as best you can.
