Are you being offered a computer with FreeDOS and will want to go to Win11 instead? I've not seen any commercial offerings for FreeDOS computers, just for the OS itself. Have you shopped for a Win11 computer and seen what bargains are available that come with Win11, not have to buy a license for Win11 to replace the FreeDOS? Just as an example, a computer can be had that came with the Chrome OS that probably could run Win11 but some of the functions may be different from a PC and Mac. Recently a client was given a Desktop that had a keyboard but the keyboard was different from those of our language, it was English but some of the keys were for UK English, key markings were different.
