Whatevergreen / AAPL00,override-no-connect no displayID support

[MythB]

It seems that override-no-connect only supports 128 bytes of edid. Because of that i cant choose more then 60hz refreshrate on my laptops internal (1440p@165hz )display. Is there any way to add 256 byte edid support? eDP port on UHD630 igpu.

here is my edid dump:
