If I understand well, i found the solution for you.
The only way that I see, is to use the API.
Using this call 'Gets the list of hosts with OneAgent deployment information for each host'
If your disabling was made since long time, don't forget to change the start time frame: and now with the integer as an entry (with a maximum of 92 days I think).
If you need more assistance not hesitate.
Ok, I think I've got it (1 year is enough and it returns more than 2000 hosts) :
Thank you for your help.
