Questions about Hermex Compatible toner for HP Color LaserJet Pro MFP M281fdw

Are these toners still compatible? HP is supposedly blocking third-party toners.

Are these cartridges compatible with an HP color laserjet MFP M283fdw? Because when I look at the colour info it says M, C, CF, Y and mine needs K (black) C (cyan) M (magenta) Y (yellow).
