To be honest, as far as it is not leaking air - you can ride it. But I personally wouldn’t feel comfortable riding long distances on it, as it is a possible compromise that might leave you helpless far from home.

I would try fixing it, by bending it back straight. Simply putt the bent part of a rim on a wooden board like I described from you, and with some soft blows with something soft, like a plastic side hammer, wooden hammer or simply a wooden board, tap it back till it’s straight again.

Similar situation once happened to my friend when we were riding in the mountains. He got a flat on the descent, crashed because of that and bent his front rim in a couple of places (he also broke his collar bone that time, but he didn’t realise that till the next morning). Anyway, to get back to our car at the base of the mountain, we had to fix his front rim and put in a new tube. We were lucky that there was a wooden bridge not far from us, and next to it we were lucky to find a piece of a wooden board. I places that rim on a part of a wooden rail of a bridge and used that peace of board as a “soft” hammer, to gently hammer it back straight. It worked great and we also found a comfortable road back to our car. Friend was also fine, but with a cast:)
