Why are our bulk enrolled devices not converting to Enterprise from Windows Pro

Question

We bulk enroll our shared devices and lab computers. They are not converting to enterprise in Intune once they are enrolled. Our staff devices convert to enterprise once enrolled, we give them to staff out of the box. I have created a policy to convert the windows pro devices to enterprise or education due to some policies not working properly with pro.

Anyone know what we can do to have the bulk enrolled devices to automatically convert to enterprise once they are enrolled? I am using up MAK keys.

Thanks
