Raw Therapee, like Photoshop, allows you to set a rendering intent. RT allows setting it globally. As apparent from this discussion, that does not mean you actually get anything but Relative.
I can print to my six color Epson from a Pro Photo RAW conversion through Photoshop manages colors and I actually get different results for each intent. I believe that means that the Epson profiles have all four intents. It makes sense that a printer would need to have them.
But I reiterate that intents are a farce. Color management is still not finished. You can't do 10 bit on a Mac. I can't set the LUT in my new Dell without buying an i1 Display Pro. ColorSync adjusts all gammas to God knows what, so it doesn't make any difference what the image profile has.
I do what any sane person would do, I get the image the way I want it, and beat on things until the inkjet looks the same. There is no magic button.
