Jun 11, 2023 at 23:23 comment added Gilby A slightly longer short answer: "The short answer is that you cannot install a version of macOS older than what came preinstalled on your Mac model when first released". So "yes", but I don't have a specific reference for the OP's MBP.
Jun 11, 2023 at 22:58 comment added David Anderson @Allan: I did not post a answer, because I do not know the answer. I posted a comment that I disagreed with your short answer. Furthermore, I do not consider any of the question links you put in the current duplicates list to contain any answers to the OP's question.
Jun 11, 2023 at 22:27 comment added Allan Short answer as in rule of thumb @DavidAnderson. I never said it was absolute, nor did I write it as a bona fide answer. If you have data to the contrary, by all means, post/point to an answer (or cast a reopen vote). I have been known to up vote answers that contradict my original assertions.
Jun 11, 2023 at 22:25 comment added David Anderson I would disagree with @Allan's comment. My 2018 Mac mini came preinstalled with Catalina. However, according to everymac.com, the preinstalled macOS is Mojave. The employees at the local Apple Store stated Mojave could be installed. Sure enough, after using my 2013 iMac to create a bootable Mojave USB installer, I was able to install and use Mojave. Currently, I have Mojave, Ventura and Windows 11 installed on the 2018 Mac mini. According to everymac.com, the 2021 M1 Pro 14 inch MacBook Pro preinstalled macOS is Monterey. I would suggest asking Apple if Monterey is possible.
Jun 11, 2023 at 19:57 comment added Allan The short answer is that you cannot install a version of macOS older than what came preinstalled on your Mac.
