It doesn’t support being flashed to a low-end commercial router like you’d do with OpenWrt, no. Those tend to require special firmware and binary blobs, hence OpenWrt has to specifically support a model or it likely won’t work. It’s like flashing Android ROMs.
OpnSense is great if you’re in the market for totally owning your own router, though. You can get an N100 box with 2 NICs off of ebay or something and slap OpnSense on that. That’s arguably more FOSS than flashing OpenWrt to a cheap commercial router.
