MATLAB: GUI, make a handle disappear

guiMATLABmatlab gui

Hey, I am MArc and I have a question about a GUI. have this GUI interface:
I want to achieve that when clicking both pink clickboxes I want to make all the red handles disappear. I tried with a function using the button 2, like this:
    methods (Access = private)
        
        function Button2Pushed(app, event,handles)
            
            value1= get(handles.PRETESSATRECTECheckBox,'Value')==0;
            value2= get(handles.PRETESSATENCASTAMENTCheckBox,'Value')==0;
            value3= get(handles.PRETESSATPARABLICCheckBox,'Value')==1;
            value4= get(handles.ntramsCheckBox,'Value')==1;
            
            if value1 && value2 && value3&& value4
                set(handles.LmEditField_3, 'Visible', 'off');
                set(handles.readelaseccim2EditField_2, 'Visible', 'off');
                set(handles.LNmEditField_2, 'Visible', 'off');
                set(handles.Inrciam4EditField_2, 'Visible', 'off');
                set(handles.AmpladadelaseccimEditField_2, 'Visible', 'off');
                set(handles.ncordonsEditField_2, 'Visible', 'off');
                set(handles.Sigma_uMPaEditField_2, 'Visible', 'off');
                set(handles.Sigma_yMPaEditField_2, 'Visible', 'off');
                set(handles.CargapermanentKNm2EditField, 'Visible', 'off');
                set(handles.SobrecargavariableKNm2EditField, 'Visible', 'off');
                set(handles.SobrecargavariableKNEditField, 'Visible', 'off');
                set(handles.PuntualKNEditField, 'Visible', 'off');
                set(handlesD_vainammEditField, 'Visible', 'off');
            else
                set(handles.LmEditField_3, 'Visible', 'on');
            end
        end
        end
But it does not work, it does nothing. I would like some advice, thank you

"I want to achieve that when clicking both pink clickboxes I want to make all the red handles disappear. "
The function you shared requires two checkboxes to be not-selected and two to be selected. That doesn't match your description.
Also, the checkbox detection needs to happen when any of the applicable checkboxes are toggled. If the detection only exists in 1 checkbox callback, toggling the other one will have no effect.
To avoid having 2 copies of the same code, assign the same CheckBoxValueChanged function to each applicable checkbox. 
function CheckBoxValueChanged(app, event)
    % Get values of all checkboxes
    cb(1) = app.CheckBox.Value;
    cb(2) = app.CheckBox2.Value;
    % Toggle the visibility flag depending on checkbox states
    if all(cb)
        visibleFlag = 'off';
    else
        visibleFlag = 'on';
    end
    app.LNmEditField_2.Visible = visibleFlag;
    app.LmEditField_3.Visible = visibleFlag;
    % etc...
end
