Is there a way to get sharp scaling to 4k out of a modded OLED switch?

One of my favorite homebrew solutions on the Playstation Vita was Sharpscale, which let you replace the linear filtering on sub native resolution games with other forms of scaling and gave access to higher output resolutions on the native OS. This was great for the PSTV as you could get near pixel perfect scaling to 1080p out. I learned that the the Switch OLED and OLED dock can actually output 4k60 and 1440p120 over USB-C, but could only find an example of this over Linux and Android. Is there something that could, say, let me integer scale 1080p to 4k on CFW, similar to sharpscale for the Vita? I want this because my TV is awful at 1080p->4k scaling.
