if you are willing to put in the work it is possible for sure.
this is probably the most asked for service i get from clients now. i have gotten win 7 to run on just about anything at this point, new or old.
first step is to just try and see if it will install. make a win 7 usb installer and see if it will even install. if it does not, then you have to do a bit more work to get started. if it installs, then all you need to do is look for some drivers once it is up and running.
question is, do you have a key for win 7? they don't sell it anymore so they are not that easy to come by if you don't already have one on hand to use.
you can make a small partition to install it to or swap out another hdd for the experiment. but do be careful if using the old drive in any way as data loss is easy. so be sure to back up anything important cause once gone it is unlikely to be retrievable.
i don't care why you want to use win 7, i still use it for my daily driver and will never move to win 10 or higher from what i can see. my clients feel the same way which is why they pay me to get win 7 running on their system. you are not alone
it is on you, however, to keep yourself safe using it, which is not any different than newer OS's really. risks are there no matter what.
