change default browser for HTML Viewer

Is there a way to change the IE browser of the HTML Viewer (cl_gui_html_viewer) in abap?

No with SAP GUI version <= 7.60.

• The note 738973 - HTML Viewer limitations explains that the HTML Viewer is not based on IE, but both are based on the same "OLE object "Microsoft Web Browser"".

Yes with SAP GUI version >= 7.70

• The note 2913405 - SAP GUI for Windows: Dependencies to browsers / browser controls explains that WebView2 can be used instead of the "MS Web Browser", by SAP GUI Options > Interaction Design > Control Settings > HTML Control > "Edge (based on Chromimum)" instead of "Internet Explorer".

EDIT July 2022: answer edited to consider SAP GUI 7.70
