[fedora-arm] Expanding Root

[brm]

System is Pine64+ with Allwinner A64 SoC. 
kernel 5.7.15-sunxi64

Fedora 32 is booting and running on this sdcard based system. However it is using a very small part of the 64GB sd card. I am looking for suggestions on how to utilize the non-partitioned space. Manjaro seems to have a script to resize the root partition and incorporate unused space into the system. Alternatively I could create a new partition and file system. This would be handy for the home directory.  How do we turn my existing home directory into a new one with its own partition?
