                Welcome to TeX.SX! How did you remove it and what is not working? The package is loaded by the document class. So you would need to comment it out there. However, fiddling with document classes provided by editors and printing houses is probably a bad idea in general. So, I would just ignore this warning.

The message about \burl being treated as a synonym for \url is a warning message, not an error message. You needn't doing anything about it -- especially if there are no \burl directives in the body of your document.
If you really can't stand getting this innocuous warning message, I suggest you open the file sn-jnl.cls in a text editor and find the following code chunk:
\gdef\breakurldefns{%
\if@pdflatex\else%
  \RequirePackage[hyphenbreaks]{breakurl}%
  \let\href\burlalt%
\fi}%
\breakurldefns%
Then, either comment out (or delete) this entire chunk or, more simply, its final instruction, viz.,
\breakurldefns%
To suppress the warning load the class with the option pdflatex:
\documentclass[pdflatex]{sn-jnl}
\begin{document}
\end{document}
