Please be patient with me on this one!

I've been out of the trade for 15 years and still miss it! I did pretty much all residential and some light commercial during my career.

Here's my scenario with my question:
This spring I was getting quotes for a backup home generator - way too expensive for a Generac automatic standby (13-14k) and I've also heard of a lot of issues with them.
I finally purchased a Pulsar PGD105TiSCO portable inverter/generator that has a bonded neutral.

I am backfeeding to our home with a 50amp transfer cord and of course a panel interlock kit.

Here's my question: Rather than convert the bonded neutral at the genset to a floating neutral, could I just not feed the ground from the genset to the panel? I would do this at the power inlet box by just not bonding the ground from the 6/3 cable to the inlet box. I'm really not wanting to open the genset and remove the bonding jumper as it may void the warranty. Plus, if I ever want to use the genset as a stand-alone I'd want the bonded neutral.

Again, be kind in destroying me if I'm barking up the crazy tree.
