Do not want to embed fonts in PDFs generated by Aspose.Cells

Aspose.Cells for Java (ver 8.5.0) is used to generate PDFs from Excel templates.
This Excel template uses MS-like fonts such as MSP Gothic.
The application is a web application and the AP server is Wildfly.

If you run this application on Windows Server, there is no problem.
However, if you run it on CentOS, the PDF will become garbled.
Judging from the phenomenon, when generating PDFs, it seems that the process is dependent on the font installed on the server side.
PDFs have a font embedding mechanism, so they're probably enabled.

[Additional note]
I checked the actual embedded font by referring to the link in labunix's answer.

PDF generated by Windows Server → garbled

PDF generated by CentOS → garbled

PDF generated by CentOS (IPA font installed) → no garbled characters

[Additional note]

Installing MS fonts in CentOS is not allowed under license.
The client environment for this application is Windows, so I would like to make it available if MS fonts are installed on the client.
I'm wondering if I could just disable font embedding.

I wonder if the guess so far is correct.
If correct, which API can I switch this setting in Aspose.Cells for Java?
