Trying to update MSI Trident 3

I recently got an MSI Trident 3 from a buddy and have been going through the process of trying to do necessary upgrades to the model (due to it being a discontinued model, and never ever used before). I’m having trouble finding what the best graphics upgrade would be for this model, as it seems like this computer exists in the abyss of unknown. I don’t even know what specific generation it is, due to it being listed absolutely nowhere on the packaging or in the system. So, i’m unable to look up upgrade specs specific to the generation. The current graphics card is an NVIDIA GTX1050. Recommendations?
