How to use app toolkits not in my config dir?

1

A bit of a noob question I guess:
I downloaded tk-config-basic-1.4.2 and set SG desktop to that config.
there is only tk-config-basic-1.4.2\hooks\tk-multi-launchapp in the config directory.
if I want to modify tk-maya, where do I get it and where do I put it?

can I grab it form a default config’s appstore?
Where does it go after that? inside tk-config-basic-1.4.2\hooks ?

You want to modify tk-maya or hooks for it?

I want to stop SG from hijacking our Maya project setting, wherever that occurs.
My local config hooks folder only has on python file:
../shotgrid/sgtk/hooks/tk-multi-launchapp/before_register_command.py

where do I get the other hooks I need?

I followed the code and see that it is using _set_project(self) in
<???>/install/app_store/tk-maya/v0.11.1/engine.py

which looks for "template_project" in
<config>/env/includes/settings/tk-maya.yml

which looks for "asset_work_area_maya" or "shot_work_area_maya" in
<config>/env/includes/settings/tk-multi-workfiles2.yml

which looks in
<config>/core/templates.yml
at this yaml blob

#
# Maya
#

# define the location of a work area
asset_work_area_maya:
    definition: '@asset_root/work/maya'
# define the location of a publish area
asset_publish_area_maya:
    definition: '@asset_root/publish/maya'
# The location of WIP files
maya_asset_work:
    definition: '@asset_root/work/maya/{name}.v{version}.{maya_extension}'
# The location of backups of WIP files
maya_asset_snapshot:
    definition: '@asset_root/work/maya/snapshots/{name}.v{version}.{timestamp}.{maya_extension}'
# The location of published maya files
maya_asset_publish:
    definition: '@asset_root/publish/maya/{name}.v{version}.{maya_extension}'

so my question is:
can I just put null for these and have SG leave the Maya project settings alone?
