TZEN not showing in STM32CubeProgrammer

[MGran.4]

Dear all,

I have a STM32L562E-DK board (DK32L562E$AT3) and when i use the CubeProgrammer GUI, I cannot see TZEN bit in OptionByte panel nor any configuration bit related to trustzone. RDP0.5 does not appear neither (only RDP0,1 and 2). The revision of my board is quite old, could it be the problem? Do i need to buy a newer board?

Best regards

Not sure what happened but performing an automated regression using script provided with TFM_SBSFU solved the problem.
