Random numbers in css and js href

Hi

I just started working on a client’s website, and I can see that js and css are called with an added series of numbers and letters, such as :
<script src='https://domaine.com/wp-content/plugins/learnpress/assets/js/vendor/plugins.all-53c696d48d605ad333f6f39911576fc7.js'></script>

How can we remove it ? It impacts cache system and so loading time.

Thanks
