Making a field Readonly in Lightning Related Record component doesn't lock field from editing

Question

I've got the following relationship

• SBQQ__Quote__c
  • SBAA__Approval__c

On SBAA__Approval__c I need to show information from SBQQ__Quote__c record.

Found that "Related Record" should work for me. I did the following:

• I've added "Related Record" component to flexipage in Lightning App Builder

• Setup "Type" field on Update Action's layout to be "Read-Only"

But whenever I open SBAA__Approval__c and view "Related Record" component - it allows me to edit "Type" field

How to make a field to be Read-Only on "Related Record" layout?
