Azure Data Disk re-sizing interview question

In Azure, you have 2 identical sizes of data disks for say 64 GB for disk 0,64 GB for disk 1. Those two data disks are attached to Windows vm
Inside the Windows VM, the disk is allocated with E drive letter and F drive letter
Here E drive disk is fully used now.so, you must resize the E drive disk alone from the portal but do not disturb the F drive disk.
How will you identify the E drive disk from the portal and resize that disk alone from the portal without any downtime of VM?
how will you achieve in Azure? Can someone answer, please
