Crete Multiple Datastores in a single LUN

Is it still posible to create multiple datastores from a single LUN in ESXi 6.7?

In our test environment I created a VMFS6 datastore on a LUN, when i tried to create a second one the disk even when i had over 600 GB of free space was not available. Searching for a kb or forum i stumbled upon an forum post saying that was posible but it was published in 2010.

Thanks
