A 2013 iMac can only go as far as Catalina 10.15.6, if you need Big Sur or later it is time to replace the computer.

The list of Mac models that are compatible with macOS Big Sur are:

MacBook Air (2013 and newer)
MacBook Pro (late 2013 and newer)
MacBook (2015 and newer)
iMac (2014 and newer)
iMac Pro (2017 and newer)
Mac mini (2014 and newer)
Mac Pro (2013 and newer)
