In last December (2019), wireguard was finally merged in the kernel 5.6.x branch. Now 5.6 is live on Fedora 32 and it is finally time to ditch the DKMS module and COPR repository to switch to the in-kernel implementation.
dnf remove wireguard-dkms
dnf update --refresh
dnf distro-sync wireguard-tools # if it was installed
dnf install wireguard-tools # otherwise
