Not that I can think of, at least not without writing a custom error handler.

This warning is a consequence of

commit 5acc54b38bf9bcd45ae8c475f19eb4b8d44ce0bf

    Internal libtiff: _TIFFPartialReadStripArray: add support for non-
conformant SLONG8 data type (fixes #2165)

Such files are non conformant and could be rejected by other software (and for 
GDAL versions >= 3.0 using internal libtiff or libtiff 4.1.0 and before that 
fix, that file couldn't be read at all), so this warning is legit and should 
be taken seriously.

3.1.0 is not yet released and is the master version, different of 3.0.1
