Can I start using DOS startup disk in Windows 10?

Question

I created a DOS system using USB flash drive. Can I change the startup mode to DOS flash drive in Windows 10? I saw someone online saying that Win11 no longer has this feature. I want to know if Win10 can do this? I know that the DOS system can be directly installed on a virtual machine, but some of the answers I have seen online are that it is possible to change the computer's boot entry and use the DOS disk to boot. I tried using USB Boot and UltraISO to create a USB DOS system, but I couldn't find the USB option during BIOS startup. I used this USB drive to reinstall the Win11 system, and at that time, I could find the USB drive option on bios. I think my USB drive should be useful. I hope to receive an answer. Thank you very much for your help!

Sea Tools for Windows has options for their software to boot using DOS (Legacy) that an opening poster reported that they had used in the past 6 months on either Windows 10 or11. The DOS legacy boot was reported not to be designed for Windows. It may be an option for trial and error testing.
