Change to M92 default settings. PDF reader customization. Is it possible?

[Reeduh]

Hello! For some reason, the thread of M92 is closed, so I'm gonna ask here. I still actively use M92 and want to change default settings of PDF reader.
I like to read in full screen and scroll pages modes. By default, these are turned off, so every time I open another document, I am forced to manually switch them on. Is there a possibility to either install more customizable third-party reader or to make some changes in the settings to make these modes switched on by default? I wonder if somewhere in memory maybe exists an editable config file for it.
I remind you that this is a Linux, not an Android model. Thanks in advance!
