Dell Inspiron 14 5458 whitelist bios removal

[Pbazfull]

So I have a Dell Inspiron 14 5458 with a I5 processor and a Nvdia GeForce 920m graphics card. I've decided to upgrade it with an egpu adapter so Ive bought the hardware. Shortly after I've learned about the whitelist thing that Dell does with their ngff ports. I'm really not that of an advanced user and I couldn't find a custom bios for my laptop yet. Should I cancel the adpter order? Also my laptop is being fixed because my Nvidia GeForce 920m had a problem and needs replacement so I can't provide you with additional info for now. I just really need to know if you guys can make a custom bios for this model so whe I get my hands on my laptop I can give you the info but if it's not possible I would like to know about ASAP so I can cancel the orders and don't was anymore money. Please help, I await anxiously your response.
