How can I use semicolon as the default list separator in my Mac's Excel?

After decades using semicolon, I am too used to it (and too old) to change. In my Windows device, I always configure the "List Separator" to ";" so I can enter formulas like this:

=TEXT(H5 ; "0.000")

I just can't find a way to do that in my Mac's system preferences, nor Excel for Mac's preferences. Someone mentioned that the only way to be able to use semicolon as list separator is by setting comma as the default character for decimal point. If that is true, some product manager at Apple needs to be tested for drugs...

Any thoughts? Please help.

Thanks
