Hi @M0HKE Welcome to the Samsung community 
I would not advise running apps from a SD card as it wil slower than internal storage, and there could well be issues with certain apps. Some apps will not support it and the Sd card speed may not be sufficient for some apps to run smoothly. Some advice on using SD cards here https://www.samsung.com/uk/support/mobile-devices/using-an-sd-card/
There is a connection for a Keyboard Dock Port for some models as can be seen on page 5 of manual https://downloadcenter.samsung.com/content/UM/202307/20230727104511258/SM-X71X_X81X_X91X_UM_EU_TT_En...
I do not work for Samsung or make Samsung Products but provide independent advice and valuable contributions.
