How I can remove the "BarCode" and "BaceCode Value" fields after disabling the Site Policy feature

We want to generate barcodes for our SharePoint online list items and documents. so we enable the Site Policy Feature:-

and then we check the bar code checkbox:-

and we added the "BarCode" and "BaceCode Value" fields to the list view:-

then we decide to use 3rpd party tool to generate the bar codes instead of SharePoint, as we will have more control on the bar codes format. so we disable the Site Policy feature + uncheck the barcode checkbox.. but the "BarCode" and "BaceCode Value" fields still show.. so how we can remove those fields on all the related lists and libraries?

Thanks
