Exclude execute from the rules allowing access to files, and only add it back for the rootfs and files labeled with system_file (/system, /vendor) or one of the types in exec_type (files under /system that cause domain transitions).

# This is the unconfined template. This template is the base policy
|
|
# which is used by daemons and other privileged components of
|
|
# Android.
|
|
#
|
|
# Historically, this template was called "unconfined" because it
|
|
# allowed the domain to do anything it wanted. Over time,
|
|
# this has changed, and will continue to change in the future.
|
|
# The rules in this file will be removed when no remaining
|
|
# unconfined domains require it, or when the rules contradict
|
|
# Android security best practices. Domains which need rules not
|
|
# provided by the unconfined template should add them directly to
|
|
# the relevant policy.
|
|
#
|
|
# The use of this template is discouraged.
