How to speed up specific tasks on gradle build for Android

Question

I ran my gradle build profiling with the following command

?./gradlew --profile --offline build

And it showed me the following time spent on tasks.

Task    Duration    Result
:app    33m25.87s   (total)
:app:packageDebug   10m52.81s   
:app:processReleaseManifestForPackage   10m52.61s   
:app:generateJsonModelRelease   10m39.84s   
:app:externalNativeBuildDebug   45.789s 
:app:externalNativeBuildRelease 12.549s 
:app:mergeDebugNativeLibs   1.350s  FROM-CACHE
:app:generateJsonModelDebug 0.373s  
... 
(many very fast tasks)

OK, so by looking at this, it seems tha app:generateJsonModelRelease, :app:processReleaseManifestForPackage and :app:packageDebug are the biggest offenders. I need help optimizing these tasks.

How can I make them run faster in my project?

My gradle.properties is already as following:

# Project-wide Gradle settings.

# IDE (e.g. Android Studio) users:
# Gradle settings configured through the IDE *will override*
# any settings specified in this file.

# For more details on how to configure your build environment visit
# http://www.gradle.org/docs/current/userguide/build_environment.html

# The Gradle daemon aims to improve the startup and execution time of Gradle.
# When set to true the Gradle daemon is to run the build.
org.gradle.daemon=true

# When set to true, the Android plugin uses the appropriate AndroidX library instead of a Support Library.
android.useAndroidX=true

# Enable Configure on demand
org.gradle.configureondemand=true

# When configured, Gradle will run in incubating parallel mode.
# This option should only be used with decoupled projects. More details, visit
# http://www.gradle.org/docs/current/userguide/multi_project_builds.html#sec:decoupled_projects
org.gradle.parallel=true

# Enable Build Cache
android.enableBuildCache=true

# Enable simple gradle caching
org.gradle.caching=true

# Specifies the JVM arguments used for the daemon process.
# The setting is particularly useful for tweaking memory settings.
# Default value: -Xmx10248m -XX:MaxPermSize=256m
org.gradle.jvmargs=-Xmx2048m -XX:MaxPermSize=512m -XX:+HeapDumpOnOutOfMemoryError -Dfile.encoding=UTF-8

I have a reasonably fast 16 core PC with Ubuntu 20.04 and expected this project to build a bit faster.
