Gradle build error

I'm using a custom gradle (I'm terrible at gradle) and I can't build for both ARMv7 and ARMv64. I'm using Unity 2020.1.6f1 this is my mainTemplate.gradle I'm trying to build for v64 just to be able to publish it to google play (so if there is other way that i can get around it please let me know)
