How to modify dimensions of vector index through neomodel on already created schema with default dimensions?

Embedding selection is configurable and up to user in my oss app that uses neo4j.

i am in process of migrating to neomodel. So i have specified vector indexes on certain properties with some default dimensions. These dimensions can change based on embedding model used so i would want to modify those on the fly post creation through neomodel.

This looks like a generic usecase but i am not able to find the right doc. Any help would be appreciated. Thanks in advance
