On yocto distribution I'm not able to mount an USB key formatted with exfat filesystem

On my yocto distribution I can't mount USB key with exfat filesystem. If I execute the command:

> blkid /dev/sda         
/dev/sda: LABEL="my-label" UUID="FC4D-5949" BLOCK_SIZE="512" TYPE="exfat"

So I'm sure that the USB filesystem is exfat, but when I try to execute the mount command I get the following error:

> mount /dev/sda /media
mount: /media: unknown filesystem type 'exfat'.

If I execute the command cat /proc/filesystems ([here](https://unix.stackexchange.com/questions/230755/how-can-i-know-if-my-kernel-has-exfat-support/230757#230757) I have found the cat command) I can find that the list of file systems supported by the kernel is:

> cat /proc/filesystems 
nodev   sysfs
nodev   tmpfs
nodev   bdev
nodev   proc
nodev   cgroup
nodev   cgroup2
nodev   cpuset
nodev   devtmpfs
nodev   debugfs
nodev   tracefs
nodev   securityfs
nodev   sockfs
nodev   bpf
nodev   pipefs
nodev   ramfs
nodev   hugetlbfs
nodev   rpc_pipefs
nodev   devpts
        ext3
        ext2
        ext4
        vfat
        msdos
        iso9660
nodev   nfs
nodev   nfs4
nodev   cifs
nodev   smb3
nodev   autofs
nodev   overlay
nodev   efivarfs
nodev   mqueue
        btrfs

exfat is missing. Could someone explained me how can I mount an exfat USB in my yocto distribution?
