Nope i think you are utesting on android 10 ( i didn’t mean the min api ) :
Android Q (Android 10 ) has restricted to access for both IMEI and serial no. It is available only for platform and apps with special carrier permission. Also the permission READ_PRIVILEGED_PHONE_STATE is not available for non platform apps.
If you try to access it throws below exception
java.lang.SecurityException: getImeiForSlot: The user 10180 does not meet the requirements to access device identifiers.
Please refer documentation: Privacy changes in Android 10 | Android Developers

Suggestion : don’t collect imei from users.
