how to activate PSNR?
SVT-AV1 calls but does not use

I'm not sure what you mean when you write 'with PSNR effect', do you mean you used 'x265 ... --tune psnr' and 'SvtAv1EncApp --tune 1' ?
('--tune 1' is the default for SVT-AV1, so it used by default and not shown in the command line, while 'minimize command line' is enabled.)
Not sure what to do with your question, you might want to ask the SVT AV1 developers, over at https://gitlab.com/AOMediaCodec/SVT-AV1/-/issues since I have don't think I can help.
