Concurrent H1 to Transfer H1 Petition

Hi I am in below situation…

Had a full time(40hrs) with Employer A with approved H1 till 2023.
Recently filed fulltime concurrent H1(40hrs) with Employer B and is still in Pending status.

Yesterday I got laid off from Employer A.
My question is can I change my pending concurrent petition (with Employer B)
to Transfer H1 petition (A --> B) by filing an amendment??

Thanks
Krishna
