Need to combine two lambda expressions in one to execute two separate conditions of one parameter

tempChoiceConfigItems is a list and has two properties, IsIncluded and IsSelected.

In the case when both of them are true then IsIncluded will take preference and for that item IsSelected will be true and all other IsSelected will be false.

Can I write that in one singe lambda expression?

if (tempChoiceConfigItems.Any(cg => cg.IsIncluded == true)) {
    tempChoiceConfigItems.Where(wtci => wtci.IsIncluded == true)
    .Select(stc => {
        stc.IsSelected = true;
        return stc;
    })
    .ToList();

    tempChoiceConfigItems.Where(wtci => wtci.IsIncluded == false)
    .Select(stc => {
        stc.IsSelected = false;
        return stc;
    })
    .ToList();
}

I did this

            if (tempChoiceConfigItems.Any(cg => cg.IsIncluded == true))
            {
                tempChoiceConfigItems
                .Select(stc =>
                {
                    stc.IsSelected = stc.IsIncluded;
                    return stc;
                })
                .ToList();
            }

Substitute all that piece of code with:

tempChoiceConfigItems.ForEach(x => { x.IsSelected = x.IsIncluded; });

tempChoiceConfigItems.ForEach(x=> {if(x.IsIncluded == true && x.IsSelected==true) x.IsSelected=true; else x.IsSelected=false;});
