Not quite sure what you're trying to say (maybe post in native language and someone can translate?), but calling that method with a boolean false doesn't cause the Bootstrap JavaScript to be hidden.

it's that mind with JHtml::_('bootstrap.framework', false); i know have alternate to hidding boostrap for exemple use "unset"
but i just experimentale and understant now with JHtml::_() how does this function necessary or not.

have error ? JHtml::_('bootstrap.framework', false, there have more params)

i views here the docs https://docs.joomla.org/J3.x:Javascript_Frameworks
i see these link for verify https://api.joomla.org/cms-3/classes/JHtml.html (only for load prefix not to hide to put " false")

--- OTHER function testing JHtml::script() than JHtml::_(). --
so if i put JHtml::script(JURI::root(true) .'/media/jui/js/jquery.min.js', true);, show :
<.script src="/media/system/js/mootools-core.js"><./script> (add line not hidden)
<.script src="/media/system/js/core.js"><./script> (add line not hidden)
<.script src="/media/jui/js/jquery.min.js"><./script> (add line not hidden)

if JHtml::script(JURI::root(true) .'/media/jui/js/jquery.min.js', false);, show
<.script src="/media/jui/js/jquery.min.js"><./script> (add line not hidden)

if JHtml::script(JURI::root(true) .'/media/jui/js/jquery.min.js', false, true); show:
still not hidden
