There are only a few days left to wait. It became known when One UI 6.1 will be released for Samsung Galaxy A53, Galaxy A54 and Galaxy S21 FE

Finally, the update will be released for mid-level models

All Samsung flagships starting in 2021 (Galaxy S21 line) have already received One UI 6.1 firmware, and very soon the update will be released for mid-level models. The software will be available for the Galaxy A53, Galaxy A54 and Galaxy S21 FE in Canada on May 14th.

As the Sammobile resource notes, new firmware for Samsung smartphones in Europe and Asia are usually released earlier than in Canada. So you can expect One UI 6.1 for the first mid-range models in the coming days.
