You can work full time once you have applied for your pgwp as you will be on implied status but do remember to stop working as soon as you receive your final grades or any other intimation that you have completed your course until you apply for pgwp
I hadn’t given my biometric though I had received a notification for it but due to COVID and being an inland applicant ,I think we were exempted. Wonder if I still have to do so as it still shows not received .
