Can I debug PHP with shared hosting?

I have VS Code installed on my client (laptop).

PHP is installed on the server. However, since its shared hosting, I can’t install anything myself (like Xdebug). Is possible to debug PHP (set breakpoints, step through code)? For example, can I use the Interactive PHP Debugger?

NuSphere PhpED IDE says that the debugger works with shared hosting. I found a tutorial on how to set it up. I’m hoping the same can be done with VS Code.
