As outlined here https://docs.aws.amazon.com/neptune/latest/userguide/access-graph-gremlin-differences.html custom vertex ids can only be set with the unquoted id property, i.e., g.addV('label1').property(id, 'customid'). How can one accomplish this using the gremlinpython package? I see an id function in gremlin_python.process.graph_traversal, but I get an UnsupportedOperationException (as expected) when attempting to use that.

You should just have to import T which is the class that hold the id and label members:
from gremlin_python.process.traversal import T
then use it as:
g.addV('label1').property(T.id, 'customid').iterate()
You can of course choose to import id from T so as to make the syntax synonymous with the example Gremlin in your question such that you may omit the T - some folks prefer that style.
It may be worth looking at the reference documentation for other common imports that Gremlin uses.
