i found solution overriding predefined dimensions adding in dimens.xml.
<dimen name="design_navigation_padding_top_default" tools:override="true">0dp</dimen> <dimen name="design_navigation_separator_vertical_padding" tools:override="true">0dp</dimen> <dimen name="design_navigation_padding_bottom" tools:override="true">0dp</dimen>
