Quadro Mosaic Query?

Hi i need some help picking 1 of these solutions for 6 x 4K Screen outputs.

Option 1: 2 x RTX 5000 NVLink SLI Bridge - each card has 4 outputs so it would make 8 total but do i need to also purchase a Quadro Sync 2 to do mosiac displays for all 6 or is the SLI bridge sufficient and if i plug in all my screens on both cards it will work as one? or do i still need a Quadro Dual Sync 2 card?

Option 2: I use a Quadro RTX4000 With a P620 + Quadro Dual Sync 2 card. Appreciate any feedback on this one cheers.
