Use the indexupgrader tool or optimize your index before using splitshard. Since this is a small index (< 5G), optimizing will not create an overly-large segment, so that pitfall is avoided.
You haven't yet explained why you think splitting the index would be beneficial. Splitting an index this small is unlikely to improve query performance appreciably. This feels a lot like an "XY" problem, you're asking how to do X thinking it will solve Y but not telling us what Y is.
