Universal TUN/TAP driver is not loading

Good afternoon!

My UNIHIKER has an OS image installed: unihiker_v 0.3.5.md5.9acbf38210ef954d5e9a0c1389830732.img downloaded from the official website https://www.unihiker.com/

For my DiY project, I need to use the tun module (Universal TUN/TAP driver), but the module does not load into the Linux kernel.

How can the problem be solved?

Information from my UNIHIKER SSH terminal:
