Running android e2e tests on circleci 2.0 using detox for react native

I am doing detox android e2e on circleci(2.0) and facing two issues -

1. circle ci (2) still does not support x86 bases emulators, so I am using ARM based ems
2. Its really slow, detox hits a timeout before even the emulator starts / app gets installed, so firebase test lab comes into picture

Is there a way to run android x86 emulators on circleci 2? and Does Detox support running tests on firebase test lab? Is there any documentation around it?

For reference, here is my yaml file for circleci

    reference:
      android_config: &android_config

            ./gradlew androidDependencies
