RadzenDropDownDataGrid restrictions on selectable items

Is there any way to restrict selectable items in multiple RadzenDropDownDataGrid?
I need to show more items than are selectable. This means that some would be disabled. They would be visible, but their state could not change.
I assumed that the disabled attribute on the RadzenCheckBox in the Template would meet my requirements, but it doesn't. Changing the value of the disable attribute does not affect the ability to change the status of the checkbox.
Thx

I suggest you fill only the required dropdown items which would be comparatively easy to implement.

Indeed there is no way to disable items. The suggestion which @Vinod_Pillai gave is a viable workaround.
