Why should I choose between two code style braces options?

I want automatically remove redundant braces except if-else construtions where any part requires braces.

But I suppose that multiline body requires braces too, but cannot select both of these options.

With first option selected I get such result:

if (!_isEnabled)
    return -1;

if (r <= _truncationRadius)
    result = DensityLaw(r);
else
    result = _truncationType switch
    {
        TruncationType.None => 0,
        TruncationType.Sharp => 1,
        TruncationType.Exponential => 2,
        _ => throw new Exception(),
    };

With second underlined option I get this:

if (!_isEnabled)
    return -1;

if (r <= _truncationRadius)
    result = DensityLaw(r);
else
{
    result = _truncationType switch
    {
        TruncationType.None => 0,
        TruncationType.Sharp => 1,
        TruncationType.Exponential => 2,
        _ => throw new Exception(),
    };
}

But my goal is to get this:

if (!_isEnabled)
    return -1;

if (r <= _truncationRadius)
{
    result = DensityLaw(r);
}
else
{
    result = _truncationType switch
    {
        TruncationType.None => 0,
        TruncationType.Sharp => 1,
        TruncationType.Exponential => 2,
        _ => throw new Exception(),
    };
}

Is it possible?
