Rig with 3xVega56 is loosing configs after touching OC settings in D/B

Hello! Vega56 owner here. When i do not touching any OC profiles, it runs fine, but HR is no more then 1.1Mh per card. If i try to apply any of overclock settings, i am getting rig with blank cfg partition. One way to fix this is clear OC profile and run reinit of configuration. So, what is the proper way to run Vegas with undervolt and with higher freqs.
