Hi,
If the quota request has been fulfilled then you should have the option to create that VM with the specified SKU size. Can you double check that the region you requested matches the region where you are trying to create the VM, but also the number of vcores you requested is within the VM size you are choosing.
Other than that, if you have just had this approved, it could be a case of waiting a bit longer, log back in again and try the above which I mentioned.
I would log a support ticket if it still doesnt show after that - or choose a VM SKU in a different region as GPU VMs are in high demand and some regions do not have the capacity
Thanks
