You can power off the machine. Otherwise, you can just use the computer. The operating system manages the details, and there is nothing you can or should try to do to upset that. Do you obsess over the number of processes, the clock frequency, the cooling fan RPM, etc? No? Then forget about memory use too. I'm seriously.

I'm not sure if your swap usage is normal or not. Swapping (paging) depends upon your personal computing habits, assuming the OS is performing correctly.

Apple on its Virtual Memory System -- https://developer.apple.com/library/content/documentation/Performance/Conceptual/ManagingMemory/Articles/AboutMemory.html

When you open an Activity Monitor session, in the memory pane, keep an eye on the "memory pressure" graphic; it's best to be in-the-green. Also find out/monitor what's using large percentages of your RAM, and determine if that usage makes sense.

If you feel comfortable doing so, you can TURN OFF disk swapping and run that way. You need to do this through the terminal and then reboot.

I've been booting and running my 2012 Mac Mini this way for months without problems, with just 10gb of installed RAM.

With 24gb you ought to be ok, but then again -- depends on how much of it that you're using.
