Destructive crop for conversion to epub

[d5364t54ytfr4]

When a PDF is cropped with BRISS and then converted to epub, the headers and footers that are cropped still appear in the epub because briss doesn't actually remove the text outside crop. It just hides it.

I use TTS to read my books since my vision is bad and for this, I need to convert the book to epub.

Can destructive crop be added to BRISS 2.0.

Or can some one atleast point to a software that postprocess BRISS cropped PDF into a PDF that doesn't destructive crop of data outside view?

Found that Santize Document in Redact under Tools in Adobe Acrobat Pro works to remove hidden content(Hidden by BRISS)
