Until now it is difficult to find sites that do not require KYC, and sportsbooks that also have most sports, I think that if you expose your case in sportsbet.io you could have a good opportunity to continue operating there as you did before, everything is question that you can communicate with support.
I doubt it'll help because OP already mentioned that it's not working on Stake so it's probably an issue with their odds provider since both Stake and Sportsbet are both powered by BetRadar.
I found one crypto sportsbook that offers the team total corners on the lower leagues like 2 Bundesliga and Championship but the unfortunate part is that they require KYC similar to stake's level 1 verification in order to make withdrawals.
