Click "File Manager" and navigate to mpmissions/<Mission_Name_Here>/cfgspawnabletypes.xml
Click the pencil icon to edit the file.
Find <damage min="0.1" max="0.4" /> for the item in question
Change the values for min and max as desired (lower value is higher durability/health and vice-versa)
If you used 0.0 for both the min and max values, it would spawn the item in with full health (pristine condition) as the minimum damage applied would be 0.0 (none) and the maximum damage applied would be 0.0 (none)
Make sure to save the file once your edits are done!
