Hello @rohanks22296e0 

Yes you can customize functionality of rest API by override below model function:

vendor/magento/module-catalog/Model/ProductRepository.php

You need to override public function save(ProductInterface $product, $saveOptions = false) in your custom module.

It may help you!
Thank you
