Programmatically remove block from layout

Question

I want to remove the product_options_wrapper block from the product view page according to the logedin user via frontend router controller.

I know that I can programmatically append a new block but I didn't find a remove function. :-(

Tried sth. like that

$this->getLayout()->unsetBlock('product_options_wrapper');

$this->getLayout()->getBlock('product.info')->remove('product_options_wrapper');

But nothing works.

Answer 1

Inorder to remove a block using its parent block use the code below

$this->getLayout()->getBlock('product.info')->unsetChild('product_options_wrapper');
