Remote work after i140 approval

Hi ! I have got my PERM certified for Location A and have my i140 approved. Considering covid19 situation, my senior manager has approved employees to work remote. I would like to move to Location B where my wife would be getting employed in a month.

Could you please let me know if H1B amendment would suffice? Or if this would require starting labor and i140 process altogether? What are my options here?

It depends on the future and if you can move back to old location at the time of your PD date getting current.
