It will suck to use gravel tires with wheel-on trainer. It will be loud, vibrate, and demolish your tires very quickly. Not recommended for anything more than using your trainer to do fitting and such.
If you want to use your gravel bike with a wheel-on trainer, you need to get another rear wheel + cassette to use with a training tire, or old slick road tires to wear through. Direct drive trainers are under $800 now as well.
I kinda lucked out and bought a Tacx Vortex on clearance last year, and a decent used road bike that basically just lives in the trainer for $500 total. No complaints with the Tacx trainer other than I don't totally trust the power numbers. Also worth considering how dirty a gravel bike gets, and whether you really want it inside, or how much time you want to spend cleaning it to ride it inside.
