I want to side load a .ipa file from a Mac to iPhone connected to Mac via USB. I don't want to use ABM or enterprise account. Also these can be any number of unknown devices. Is there any way to set this up automatically?

We have a .ipa file that we need to side load on iPhone via USB connected to a MAC. IPA file will be on MAC. We can't use enterprise license. We have a business use case where we need to side load the app. Any way to do that or can be reach apple support for this? Please help. Note: The iPhones attached will not have the Apple ID logged in. There are companies who are side loading the app for business purpose on the customers phone.
