1*10 would be relatively easy to do. You’ll need a cassette and nw chainring, and a new chain, but you need that anyway.
On top you’ll need a shifter and rear mech, ideally a shadow+ clutch (assuming Shimano, other brands are available)
That’s the base level to do it. It’d give you a 30/36 lowest gear (0.83) if you get a 30t chainring. Currently you have a 22/32 = 0.69, so your lowest gear would be substantially harder, equiv to 22/27 so about your current third gear on the rear cassette.
Could you get by on that? Why not try it?
If not then you get into extender cogs, which do work well. A 40t extender decreases your lowest gear to 0.75, so about gear 2 on your current setup, or as above a 42t extender gets you pretty close. However, ime a 40t works without major shenanigans with b limit screws, etc; a 42t MAY need a derailleur cage offset thing to work smoothly. Others MMV.
Or, you could go straight to 1*11, and get the range ‘built in’ without resorting to aftermarket fixes. But that’d cost a fair bit more and may need new hub / freehub body. I’m no expert on 1*11 to know what level it’s reached so far and how backward compatible bits are though, someone else will answer that better than me.
