Keep underscore symbol using latex as interpreter

Hello All,
I am trying to have one of the entries for my legend (which I like to have latex interpreter for) be the string to the data set I am analyzing (see image). And thus, I want to keep the underscore symbol as is (instead of making what follows a subscript) but still keep the latex as interpreter. I know that making interpeter 'none' it will ignore the subscript, but I want to keep the _ symbol in the legend AND use latex interpreter.
I have not figured out a way to do this (in the attached image, latex doesn't understand the dataName variable so it prints in a different font from the rest of the legend). I want the fonts to match.
Hopefully this makes sense![](https://www.mathworks.com/matlabcentral/answers/uploaded_files/1697066/image.png)

This text call uses _ to make x a subscript of a.
text(0.25, 0.25, "Text with $a_x$ and LaTeX interpreter", Interpreter = "latex")
This text call uses \_ to include a literal underscore.
text(0.25, 0.75, "Text with $a\_x$ and LaTeX interpreter", Interpreter = "latex")
You can use replace to perform the replacement if you are reading the string you want to use as the legend label from a file.
s = "Text with $a_x$ and LaTeX interpreter"
s2 = replace(s, "_", "\_")

plot(0, 0, 'o', 'markersize', 20), grid on
legend('{$03 \textunderscore$May$\textunderscore 2024 \textunderscore$NoHS$\textunderscore 09$}', 'Interpreter', 'LaTeX', 'fontsize', 16)
