iOS 26 AttributedString TextEditor bold and italic

Is there a way to constrain the AttributedTextFormattingDefinition of a TextEditor to only bold/italic/underline/strikethrough, without showing the full Font UI?

struct CustomFormattingDefinition: AttributedTextFormattingDefinition {
	struct Scope: AttributeScope {
		let font: AttributeScopes.SwiftUIAttributes.FontAttribute
		let underlineStyle: AttributeScopes.SwiftUIAttributes.UnderlineStyleAttribute
		let strikethroughStyle: AttributeScopes.SwiftUIAttributes.StrikethroughStyleAttribute
	}

    var body: some AttributedTextFormattingDefinition<Scope> {
        ValueConstraint(for: \.font,
            values: [MyStyle.defaultFont, MyStyle.boldFont, MyStyle.italicFont, MyStyle.boldItalicFont],
            default: MyStyle.defaultFont)
        ValueConstraint(for: \.underlineStyle,
            values: [nil, .single],
            default: .single)
        ValueConstraint(for: \.strikethroughStyle,
            values: [nil, .single],
            default: .single)
    }
}

If I remove the Font attribute from the scope, the Bold and Italic buttons disappear. And if the Font attribute is defined, even if it's restricted to one typeface in 4 different styles, the full typography UI is displayed.
