How to alter an embedded entity form? [#2878959]

I would like to alter an entity-create/edit form, but only when it's used as an entity form in an entity browser. I've tried a hook_form_alter and a hook_form_FORM_ID_alter, but haven't found the built-out form array to alter, containing the actual fields of the target entity. What I specifically want to do is set the value of a select list and hide it. Could someone point me in the right direction for doing this type of alteration?

Solution below worked out using form pre render.

function MY_MODULE_form_entity_browser_MY_FORM_form_alter(&$form, FormStateInterface $form_state, $form_id) {	
   $form['#pre_render'][] = 'MY_MODULE_pre_render';  
}

function MY_MODULE_pre_render($element) {
	/* dpm($element); */
	/* examples */
	$element['widget']['inline_entity_form']['title']['widget'][0]['value']['#title'] = t('This is a test');
	$element['widget']['inline_entity_form']['title']['widget'][0]['#prefix'] = t('This is a test');
	$element['widget']['inline_entity_form']['title']['widget'][0]['value']['#maxlength'] = 9;
	$element['widget']['inline_entity_form']['field_my_field']['widget'][0]['value']['#value'] = t('This is a test');
	$element['widget']['inline_entity_form']['field_my_field']['widget'][0]['value']['#default_value'] = t('This is a test');
	$element['widget']['inline_entity_form']['field_my_field']['widget'][0]['#access'] = FALSE;  
	return $element;
}
