Avamar Bare Metal Restore physical to VM which drive capacity different

I'm doing Avamar Bare Metal Restore from physical server to Scale VM, it has below error when i try to restore, my physical server having Avamar VSS snapshot Volume C and D (D drive only use less than 300GB) but in VSS it capture the whole storage which is 10TB.

My Scale VM allow only maximum storage up to 8TB per drive and I'm unable to assign 10TB for drive D in my Scale VM. As i read through the Avamar BMR it should have minimum or more than original drive to be restore. Is there anyway to overcome this ? Need assistance from expert.
