XPS 13 9310 Resizable BAR (Feature Request)

Question

I'm not sure which laptops this is and isn't available for but my XPS 13 9310 does not currently support Resizable BAR. As far as I'm aware, all it would take it a BIOS update to allow this to work. It would benefit anyone that uses an eGPU with a relatively new GPU. I know there isn't much (if any) official support for eGPUs but I don't see what negatives would come from this. This is something that I think should be pushed to all laptops with Thunderbolt 3/4 and/or a dGPU.

If anyone has a better way for me to request this feature, please let me know. Intel Arc GPUs rely on this technology and I would love to try one out with this laptop. I think it would perform very well thanks to Intel Deep Link.

I'm also looking for this but for my XPS 13 2-in-1 9310. I have a custom eGPU setup and would love to switch to an Intel Arc GPU but I have no toggle in the BIOS for resizable BAR.

Same here, been trying to find a 'feature request' forum. ReBAR seems like it should be an auto-include for thunderbolt 2-in-1's. I'm on a 9315 model and hoping they release a bios update for ReBAR.
