HTC A9 S-ON no OEM unlock

[getz111]

So today i've got A9 from the shop with a demo software (its a fully working device just got a version of MM with sim card part disabled). Problem is that its S-ON and cant turn on Developer options to turn on Oem unlock, its all greyed out. Tried sunshine method but it doesnt work. Any ideas?
