It’s not just the Galaxy A51 and M30, the Galaxy A71 5G also receives the One UI 3.0 update with Android 11. This software, A716USQU2CUA7, also includes the January 2021 security patch.
Again, this is for the 5G version of the A71 (SM-A716U). The 4G version of the phone (SM-A715) will have to wait a bit longer (the original schedule called for the A71 phones to be updated in May).

Android 11 and One UI 3.0 are coming to the Galaxy A71 5G
