IMHO, in each case it is not a idea to backport openvpn 2.6 unless network-manager-openvpn supports to override also --data-ciphers.
Packages are not upgraded to backports-versions by default. You have to opt-in (either manually or by adjusting pin-priorities in apt-preferences) to upgrade to 2.6.
Since the version of network-manager-openvpn in bullseye even works with the backported openvpn for the majority of not-outdated configurations there is nothing to be fixed here.
Unless you have another convincing argument I intend to close this bug in a couple of days.
