If you’re running into problems caused by concurrent inserts and you’re on SQL Server 2019 or above, it’s worth testing out OPTIMIZE_FOR_SEQUENTIAL_KEY. This may alleviate those issues by handling inserts a little bit differently to reduce contention. OPTIMIZE_FOR_SEQUENTIAL_KEY will “control the rate at which new threads are allowed to request the latch, and favor threads that are likely to keep the throughput high.”
