This update adds FSR3 and DLSS support into the infantry beta. You can select which upscaler you want to use in the Video Settings and selcting your option from the Anti Aliasing & Upscaling drop down. There's a number of options for the upscalers plus you also choose SMAA, DLAA & FSRAA as anti-aliasing only options if you don't want to use the upscalers. DLSS/DLAA are nVidia only options - if you do choose them and you don't have a compatible GPU then it will fall back to SMAA. FSR3 should work on any GPU.
