Clock [Q] Hi all

I bought a nexus 7 from a pawn shop yesterday its secure boot locked only paid $40.00 for it .
But is there any way to reset with secure boot locked. they sold it as is becuae they didnt have the passowrd from the original owner.
and they couldnt get in contact with them.
I can go to recovery just cant perform a wipe will adb help with this?
