Python 里面有库可以直接删除 pdf 内容里面的某个元素吗？

我通过 PyPDF2 读取 pdf
{'/Parent': IndirectObject(1, 0), '/Contents': IndirectObject(22, 0), '/Tabs': '/S', '/Resources': {'/XObject': {'/Image5': IndirectObject(23, 0), '/FormXob.86cdf15f1994e2f2b7032e461afd4234': IndirectObject(25, 0)}, '/ExtGState': {'/Xi0': IndirectObject(26, 0), '/gRLs0': {'/ca': 0.13}}, '/Font': {'/F1renamed': {'/Encoding': '/WinAnsiEncoding', '/Type': '/Font', '/Name': '/F1', '/BaseFont': '/Helvetica', '/Subtype': '/Type1'}, '/F1': IndirectObject(27, 0), '/Xi2': IndirectObject(35, 0), '/Xi1': IndirectObject(38, 0)}, '/ProcSet': ['/Text', '/ImageC', '/ImageB', '/PDF', '/ImageI']}, '/Group': {'/Type': '/Group', '/S': '/Transparency', '/CS': '/DeviceRGB'}, '/MediaBox': [0, 0, 720, 405], '/Type': '/Page', '/StructParents': 0}

我现在想把 FormXob.86cdf15f1994e2f2b7032e461afd4234 这个内容删除，请教能直接删除吗？
