I wonder if there is a possibility to model an interference fit, like peg-in-hole application.
As far as I see from "Spatial Contact Force" block examples or Simscape Multibody Contact Forces Library (https://www.mathworks.com/matlabcentral/fileexchange/47417-simscape-multibody-contact-forces-library), it is not possible to model this type of contact.
What I need to model is insertation force, friction force and normal forces.
Any help would be appreciated.

The interference fit is a complex phenomenon to model. I think that I would approach this as a prismatic joint with external friction modelled with pure Simscape.
For that purpose, you need a translational interface linking Multibody and Simscape.

Best of Luck Juan
