Hello,
I saw that on the instagram of digital storm, they made a pc with 4 2080 ti. But how they will do to make them work together knowing that the nvlink supports 2 rtx max.They put a bridge sli?

4 x RTX 2080 Ti in a build doesn’t mean they’re all in sli.    You can run them separately, or 2x sli and the other 2 individual, etc.   Some apps and Crypto make good use of individual cards for separate tasks.

NVidia has been backing away from sli support for some time.  The new RTX 2070 doesn't even get 2 way sli support and has no NVlink connector for a bridge.  You need to go to the RTX 2080 or higher to sli.

Above 2 way sli is just not supported anymore on the new cards.  

I haven't spent a lot of time on this, so if something has changed then good.  Otherwise, 2 way is it for RTX.

Look up AMD Infinity Fabric. That will be how you would 4 cards but that is also AMD not Nvidia lol.

Do you think they will create a nvlink for 3 or 4 rtx cards to work together (for enthusiasts or professionals)?

Doubtful, as bprat mentioned. Nvidia is going away from SLI and few games actually use it to begin with.
