Obviously there is the use VPN thing but if an exchange requires KYC, then obviously you cannot do this.
there's still some exchange that you can use without any KYC requirements such latoken , but you know there's a certain coins to trade only as well within that platform, and also there's a swap sites where you still can trade your coins, and for me probably that's the good option if you have such issue in your country., wherein you can connect your wallet to the site and you can use their swapping service without any requirements just make sure you have balance for gas fees..
