No problem.

Edit:
One thing more: trying to check whether there are another variants of fdisk (i.e. cfdisk, sfdisk, parted) I issued find command with result bellow
find / -name \\*disk
/sys/class/scsi_disk
/sys/devices/platform/soc/soc:internal-regs@d0000000/d0058000.usb/usb3/3-1/3-1:1.0/host0/target0:0:0/0:0:0:0/scsi_disk
/usr/sbin/fdisk
showing first that there is only fdisk command present (which should be included manually, as shown by AreYouLoco
(Fdisk is missing on newly installed Turris OS?) using opkg update and
opkg install fdisk), and, second, that - if I understand it well - there is USB3 driver used.
Edit2:
Parted could be installed in simillar way.
