Does Sharepoint Indexer for Azure Search support Alternative chunking methods or configuration parameters?

Dear Team,

i recently discovered the Sharepoint Indexer and it is quite helpful for us to set up an initial prototype. We are thinking of migrating to a custom build solution (with Microsoft Graph - as broadly described in the tutorial).

That is mostly, because I could not find any documentation about if there are ways to tweak the indexer, so that he uses a different chunking strategy or limit the chunk size.

So Is there something like this or a feature / full version of this with more configuration planned or is it advisable to build something custom in the long run?

Thank you so much!
