You can use 'set' to change the 'Enable' property of the dropdowns in the callback functions.

Here's how you can modify the code to include lines -

    % Callback function for the first dropdown
    function firstDropdownCallback(~, ~)
        % Disable the second dropdown
        set(secondDropdown, 'Enable', 'off');
        % Enable the first dropdown (in case it was disabled)
        set(firstDropdown, 'Enable', 'on');
    end
    % Callback function for the second dropdown
    function secondDropdownCallback(~, ~)
        % Disable the first dropdown
        set(firstDropdown, 'Enable', 'off');
        % Enable the second dropdown (in case it was disabled)
        set(secondDropdown, 'Enable', 'on');
    end
