You can try changing the default flags for the architecture you are about, for example https://android.git.corp.google.com/platform/build/soong/+/master/cc/config/arm64_device.go#49, but it is likley to cause build problems in a few modules. For example, ART sets strict stack frame size limits that will probably fail with global -O0.
