Install DKMS on Rhel8.8

Newbie here. I want to install dkms for my RHEL 8.8. I learnt that its not supported on RHEL and has to be fetched via epel. I ran the below step yum install /home/abhi/Downloads/epel-release-latest-8.noarch.rpm and got success for it. But ran into below errors [root@localhost src]# sudo yum install dkms Updating Subscription Management repositories. Extra Packages for Enterprise Linux 8 - x86_64 0.0 B/s | 0 B 00:02 Errors during downloading metadata for repository 'epel': - Curl error (60): Peer certificate cannot be authenticated with given CA certificates for https://mirrors.fedoraproject.org/metalink?repo=epel- 8&arch=x86_64&infra=$infra&content=$contentdir [SSL certificate problem: unable to get local issuer certificate] Error: Failed to download metadata for repo 'epel': Cannot prepare internal mirrorlist: Curl error (60): Peer certificate cannot be authenticated with given CA certificates for https://mirrors.fedoraproject.org/metalink?repo=epel 8&arch=x86_64&infra=$infra&content=$contentdir [SSL certificate problem: unable to get local issuer certificate] Error: Failed to download metadata for repo 'epel': Cannot prepare internal mirrorlist: Curl error (60): Peer certificate cannot be authenticated with given CA certificates for https://mirrors.fedoraproject.org/metalink?repo=epel- 8&arch=x86_64&infra=$infra&content=$contentdir [SSL certificate problem: unable to get local issuer certificate] Any idea what's going wrong or how to fix ?
