Android GearVR through CloudBuild: Can I set signiture schema v1 to sign the apk?

We rely on Cloud Build to build both test and release apks for android. We recently noticed that in new Unity version, signiture schema v2 is used, and these apks can’t be uploaded to Oculus Gear Store.

How to set signiture schema v1 in Unity and works with Cloud Build?

I am not an expert on the matter, but isn’t it possible to re-sign the APKs ? i know this is a hassle, but still a possible workaround…
