Your research is incorrect. However, you are using the wrong terminology.

VFAT is not a disk format.

FAT16 is a disk format. So is FAT32 (introduced in Win95 OSR2 in 1996):
https://en.wikipedia.org/wiki/File_Allocation_Table#FAT32

Two full decades more recently than that, so is exFAT (introduced
2006, made open 2019):
https://en.wikipedia.org/wiki/ExFAT

FAT12 is also a disk format but from the early 1980s and rarely seen now.

VFAT is a system for storing long file names on FAT drives, and it
applies to both FAT16 and FAT32.
https://en.wikipedia.org/wiki/Design_of_the_FAT_file_system#VFAT

FAT16 means a maximum disk size of 2GB-1kb, so you're not using that.
That _implies_ that your disk is FAT32 but we don't know for sure.

If you enable exFAT support:

... and reformat the disk with that, it should AIUI enable support for
larger files.
