Can I install an uncertified eSIM profile provisioned by myself on Android?

I would like to set up an SM-DP+ server to provision my own eSIM profiles. These usually get certified by GSMA and are used for large-scale Remote SIM Provisioning, but I would want to use this for home testing only, so getting official certification would be overkill. I understand that I will need my own mobile network to work with it, which I also want to set up at home. My main concern is that either Android or the device manufacturers impose limitations that would only allow certified eSIM profiles to be installed on a device. I was thinking of using a Google Pixel 3A for testing, so I would be installing the eSIM profiles on this phone. I also tried to find information on what's inside a SIM profile but there isn't much on the internet. I know it contains ISMI and some shared keys which it uses to connect to the MNOs network. I would like to know what else is needed to create a functional eSIM profile and set up a server that provisions these to a Google Pixel 3A for a mock cellular network.
