You've got the bios's problem.
Google showed this site;

According to this, USB booting is not possible unless Lenovo ThinkPad T470 Boot from USB using Rufus is installed. The link to rufus-3.4.exe on this site is broken, but you can find it at;

Good Luck & Best Regards,
"What is Boot from USB? It is a process of starting a Computer operating system from the USB drive". The above definition is wrong, what the article talks about is booting from a usb storage chip plugged into a usb port. What "I" have in mind is booting from a sata-ssd connected to a sata/usb-adapter and that connected to the usb port. The thunderbolt port is even better if it gives more speed and it can also be ramified as a manifold or dock. The article talks about booting an OS on a usb stick (live if you want any speed, actual RW if you want something slower than a dead dog). The typical OS drive I use is a 1tb ssd in a mobile rack that has a whole host of 100gb OS partitions of different distros. This will next change to 4tb, if I have to create it with windows that's a definite deal-breaker. I'd want to just plug this ssd or a copy of it into a sata-usb adapter and that into the usb port of the laptop and select the system to boot when grub shows me its boot menu. If I can do this I'm happy. If I cannot, then I split the laptop's onboard ssd and install my stuff on the larger 2/3 of it (I think such was your first advice too). Others suggest to install another ssd in the laptop in lieu of some unused device. That's Season-1/Episode-1, the saga will continue when I get my 1tb replacement T470 :-)
