Pls Suggest compatible SSD for my Asus Rog laptop?

Hi,

I bought ASUS ROG Strix GL503GE-EN269T Core i5 8th Gen - (8 GB/1 TB HDD/256 GB SSD/Windows 10 Home/4 GB Graphics/NVIDIA GeForce GTX 1050 Ti) GL503GE-EN269T Gaming Laptop (15.6 inch, Traditional Black, 2.6 kg) from Flipkart in 2019.

It already has a KINGSTON RBUSNS8154P3256GJ SSD. Please check the attached pics of the SSD. I believe, if I am not wrong, it is a M.2 **SATA **SSD which is connected to m.2 port, right?

Now I want to upgrade the SSD but I am not sure if my laptop will support a NVme SSD or not. I am thinking of buying Samsung Evo nvme SSD so wanna be sure if it is compatible.

Try this Crucial tool:

I had the Asus FX553VD with 7th gen i7, came without an SSD and 1050. It supported NVMe so this laptop should certainly support it.
