move either units from interface section to implementation section.
e.g.

interface
uses MyUnitU -->>> Move from here

implementation
uses MyUnitU  ->>> to here

Moving a unit from interface section to implementation section doesn't affect any other code. you can define /use variables the same way.

Can you clarify what exactly you want to do?

I have the main unit, then I`m creating a class where I want to declare a variable of a type that is defined in the main unit. or let`s say use a constant from the main unit.

unit MainUnit

const
  MyConst = 1000;


unit MySubUnit

interface
  procedure MyProc;

implementation
procedure MyProc;
MyVar : Integer;
begin
  MyVar := MyConst;
 
end;
