My phone is disabled and the screen says hook up to iTunes how can I Able my phone without hooking it up to a Mac computer

You need a computer, a macOS or a Windows OS.

If you don't have a computer, ask a friend or relative to use their computer. 

Alternately, visit your local Apple Store or Apple Authorized Service Provider and they should be able to help you out.

You will first have to make an appointment due to the pandemic.
