What is the best way to get my Samsung Note 3 SM-N900V to at least Nougat 7.0?

The step by step examples have holes in their solution for one reason or another. I need to: a. USB debug (easy) b. Root w/o KNOX violation c. Install TWRP d. Flash a ROM like Apply a custom ROM like RR-N-v5.8.2 Has anyone done this in 2020? It seems like links for these solutions vanish for some reason. This like ArabicTools and Root_de_la_Vega-SM-N900V.7z seemed to have vanished.
