Biblatex \citeauthor style (number of authors and remove et al. underlining)

Question

I am using biblatex to get the \citeauthor command. However, I wish to edit the output of that command and have not yet found how to achieve what I want.

I'm importing biblatex as:

\usepackage[
    style=ieee,
    isbn = false,
    url = false,
]{biblatex}

And have this following reference:

@inproceedings{raster-to-vector,
    author = {Liu, Chen and Wu, Jiajun and Kohli, Pushmeet and Furukawa, Yasutaka},
    title = {Raster-To-Vector: Revisiting Floorplan Transformation},
    booktitle = {Proceedings of the IEEE International Conference on Computer Vision (ICCV)},
    month = {Oct},
    year = {2017}
}

When I use \citeauthor{raster-to-vector}, I wished to get a simple "Liu et al." (first author followed by et al.). However, this is the current output:

It contains the last name of the first three authors and only then the et al.. Also, I'd like to remove the underline that is currently shown. Thanks in advance.

Answer 1

I have found a solution. I changed mincitenames and maxcitenames for changing the number of authors, and used this answer to remove the underline. The final commands are as follows:

\usepackage[
    style=ieee,
    isbn = false,
    url = false,
    mincitenames = 1,
    maxcitenames = 2,
]{biblatex}
\DefineBibliographyStrings{english}{%
    andothers = {et\addabbrvspace al\adddot}
}
