how to disable the checked checkbox of a datatable

I created a table follow the example here: RStudio Shiny list from checking rows in dataTables

But I want it has other features: I want to have some rows of the data table are checked as default, and disable those pre-checked rows that the user can't uncheck them, they can check/uncheck other rows.

The checked rows information (including pre-checked and user-checked rows) will be used in later steps.

Anyone knows how to do this?
