Hi @ClintBoaz1,
Does either of the below suit your workflows?
@DonMorrison1 is correct, where/how the original is published can affect overwriting.
ArcPy
You can publish from ArcGIS Pro manually or programmatically. Check out my blog post here for publishing with ArcPy. When overwriting you just need to add in the code on line 77 below. Even if you initially publish manually from Pro, you can still use Python (ArcPy) to overwrite.

There are more advanced workflows for publishing and overwriting that digs into the xml for various setting, you can find these in the documentation links at the top of the script. The above is really a minimum required to publish/overwrite.
ArcGIS API for Python
Publish an original Feature Service based on the File Geodatabase.
from arcgis.gis import GIS
from arcgis.features import FeatureLayerCollection
## Path to File Geodatabase Zipped
gdb = r"C:\path\to\zipped_gdb.zip"
## Properties
gdb_properties = {"title" : "PUBLISHED_FROM_API", "type" : "File Geodatabase"}
## Access ArcGIS Online
agol = GIS("home")
## Add File Geodatabase to AGOL
gdb_item = agol.content.add(item_properties=gdb_properties, data=gdb)
## Publish as new feature service
new_fs = gdb_item.publish()
print(new_fs.id)
## you can delete the File Geodatabase added to AGOL
Overwrite...
from arcgis.gis import GIS
from arcgis.features import FeatureLayerCollection
## Path to File Geodatabase Zipped with data to use to overwrite
gdb = r"C:\path\to\zipped_gdb.zip"
## Access ArcGIS Online
agol = GIS("home")
## Fature Service as an Item object - the one to overwrite
item = agol.content.get("ITEM_ID")
## Overwrite
flc = FeatureLayerCollection.fromitem(item)
print(flc.manager.overwrite(gdb))
Note! The name of the file geodatabase and the feature class(es) must be the same as the original that was published or else you will get
ValueError: The name and extension of the file must be the same as the original data.
I hope that helps.
All the best,
Glen
