eth_getUncleCountByBlockNumber

Returns the number of uncles in a block from a block matching the given block number.

While this method is supported, the BSC network uses the Proof of Staked Authority ( PoSA ) consensus mechanism which doesn't involve 'Uncle' blocks.

Hence all results from eth_getUncleCountByBlockNumber will always return 0x0.
