Removing Default list form style

[Luigi_cff]

Is there any way I can remove this from my Sharepoint List Form ? Because I have stylized in power apps.

@Luigi_cff This is not possible to hide using Power Apps or SharePoint OOTB capabilities.

You have to inject custom CSS to hide these HTML elements using SPFx application customizer. Check below threads for more information:

2. How can I include the same JS and CSS files on multiple SharePoint Modern Page? 

Note: DOM manipulation & CSS customizations are not recommended by Microsoft and some of your customization may break if Microsoft changes HTML element id/classes in new release updates.
