Yeah the novelization isn’t canon.
This link goes over the links between the EU Han Solo origin book and the new movie. I suppose not all that surprising giving how much TFA seemed to draw inspiration from the EU (despite his claims he wouldn’t). It’s actually pretty funny because when Kasdan was hired to write the character based spinoff, he said he wouldn’t look at the EU at all and wanted to do something new. Perhaps it was his script of Boba Fett being a name used by someone wearing the armour that was based on this claim, which didn’t happen obviously.
If you got the link I’d be interested to read this.
