Since I could not find any information about the topic, decided to post the question on this forum. Though IBM has continues updates for the switch, Lenovo has an option to run CNOS with much better feature set. Lenovo version of the (I assume) same switch is much pricier.
I did try to just update to Lenovo ENOS but IBM switch will not accept the firmware, as expected.
