You can find patrol zones in regions.xml or CustomRegions.xml if using Ultimate Backup.
My mod has several important differences compared to Tom's config. It includes EUP backup for the default backup menu and Ultimate Backup, additional stations, more suspect drop-off areas, and the ability for EUP uniformed officers to patrol in local jurisdictions, provided that callout developers allow it. Additionally, I customized the ambient spawning system so that EUP uniformed officers patrol in their respective jurisdictions.
Yes, the custom folder automatically applies changes to the LSPDFR data settings.
You only need to change Ultimate Backup files, if you use Ultimate Backup.
You go to agency_eup.xml and under the patrol section, you can replace what vehicles respond.
agency.xml isn't made for EUP uniformed peds as it is formatted for replacement peds you see in story mode.
Rangers specifically respond in the Grand Senora, designated as a national park zone. To remove the regions, you can edit the regions.xml file. Navigate to the NPS section and change "DESRT" to another department. Then, move all "DESRT" lines from CustomRegions.xml to the new department.
