Can I install macOS Sequioa on a partition on my late 2012 iMac’s HHD?

I would like to install sequioa/sonoma on my 2012 iMac, but I don’t want to risk the data that I have on it, so can I create a partition on the iMacs HHD and install sequioa/sonoma on one partition and keep all the stuff I have on my iMac safe on the other Catalina partition?

The iMac is a Late 2012, Quad Core i5, Nvidia GeForce GT 650M, 8GB RAM, 1TB SSHD (Hybrid Drive)
