Answer 1

Find the block name of "Related Posts" by enabling Template Path Hints and Block Path Hints in Store->Configuration->Advanced->Developer->Debug. Set Template Path Hints and Add Block Names to Hints to yes. Refresh the cache and find for the block name in Product Detailed Page near to Related Posts tab.

Look for the block name in catalog/view/frontend/layout/catalog_product_view.xml and remove it.

<referenceBlock name="reviews.tab" remove="true"></referenceBlock>
