Hi

i have dell xps 9360 ( kaby lake i7 intel 620 )

when i installed qubes after installation the qubes didnt succeeded to start .

work around that worked was to remove from grub the iommu=no-igfx and after this

everything went well . is there an issue to add this option ?

i have qubes 4 rc1 ( latest testing repo kernel 4.9.54-21 .

No, it should even be more secure that way. Apparently the Qubes devs
only added it due to some problems without it (which you don't seem to
have). There's a related bug @qubes-issues.

But when i add this the computer cant load qubes . It restart the machine .

(thought you meant remove here)

This is about having that option removed:

Yes, keep it removed.
