Hi @MarekBelisko,
Yep, CONFIG_ENV_IS_NOWHERE will definitely break the integration. So this is in the default config of u-boot-imx somewhere? 
I’m just giving your board integration a spin, and to be sure, we’re talking about this one? iMX93 Industrial Development Kit Lite | VOIPAC TECHNOLOGIES s.r.o.
Does it need additional layers, so I can construct the kas file for the auto builder?
Greetz,
Josef
