Case anyone is interested.
All you have do is excluded the 64 bit or 32 bit depending what you want to capture.
You can also leave out the display version if you only want to capture a total of deployment agents.
select guid from vcomputer vc
join inv_addremoveprogram iarp on vc.guid=iarp._resourceguid
where iarp.displayname like 'Altiris Deployment Agent'
and displayversion ='1.0.0'
