@Mona AlOtaibe Thanks for posting in our Q&A.
For enrolling iOS devices to intune, there are some methods. Please read the following article:

ADE enrollment configures settings using Apple Business Manager (ABM) or Apple School Manager (ASM). Apple Configurator and BYOD don't need to configure in ABM or ASM.
Hope it will clarify something.
