You can do it something along this. Ofc, you need to build logic to go through your services and then on loop update their item properties but you get the idea.
from arcgis.gis import GIS
import getpass
password = getpass.getpass("Enter password: ")
gis = GIS('org', 'me', password)
print("Connected to: {}\nConnected as: {}".format(
gis.properties.urlKey + "." + gis.properties.customBaseUrl,
gis.users.me.username))
search_result = gis.content.search(query="title:Liikenneväylät Helsinki", item_type="Feature Layer")
search_result
copy_to_item = search_result[0]
print(copy_to_item.extent)
item_properties = {
'extent' : '[[24.831, 60.136], [25.253, 60.295]]'
}
copy_to_item.update(item_properties=item_properties)
print(copy_to_item.extent)
