I had in mind "hackintosh" in which people are disabling IGPU

Isn't this command disables dGPU, is it?
Anyway, entering this command follows the same execution principle as in other EFI shells, which is not allowed in your bios. Are you already convinced of this trying to change the variables?

You're right. This bios is completely blocked. Can't even dump bios file via software. As you said, any modyfications only via ISP programmer

I have some questions. When i make myself to try flash bios via ISP can I flash latest modded bios without RSA keys? or I should use bios which wasn't encrypted in the first place?

Save a copy of your BIOS with a programmer, and then you will need to modify it.
Encryption state and RSA keys are different things.
