@DiptangshuChakraborty-6090 Apologies for the delayed response here. If you choose the storage account type of General-purpose v2 you have the ability to use read-access geo-redundant storage(RA-GRS) or read-access geo-zone-redundant storage(RA-GZRS). See Read access to data in the secondary region.
Unfortunately at this time FileStorage accounts only support LRS and ZRS. One option might be to utilize share snapshots then restoring the files to the other storage account.
Hopefully this information was helpful to you. Let us know if you have further questions or issues and we will be happy to help.
