Possible to assign material to Runtime Text?

Hi I’m trying to place plain texts in scene but I’ve the negative way in both cases (runtime and offline), at the beginning I tried to put in a Widget (UMG) a Font Material, but looked here around I’ve realized is not possible (at least nowadays), then I’ve tried like text render but the inconvenience can’t play with the alpha property (in Text Render Color) so then I way back to try in a Widget like a Runtime Font but now I’ve the incovenience the text renders with too much bright reflection (show in a picture):

Somebody can tell me how to take it out and confirm me if is not possible to assign a material to Runtime Text to avoid the specular?

How did you do this?

I’m also interested in adding font material to runtime font to create a gradient
