No such bypass. I highly doubt there ever will be a bypass for this. The reason being when you xray (and you see all those ores), those ores are ACTUALLY there. So when you see the entire floor made of those diamond, gold, iron ores. Those ores, are physically there on the server. They will change back to their true value once the block is in visible sight. So all blocks in visible sight, are what the blocks actually are. All blocks underground/non-visible are physical ores (however, once they are in visible site, they will change to its true value).
