They are listed under the "HiWy - " parameters. There are a handful in the scalars near the beginning of the XDF. Be sure to set the minimum MPH to a minimum of 45 - 50 MPH. Too low causes driveability issues: HiWy - Min MPH

The table of commanded AFR versus load is about halfway down through the tables. Right after the AE tables:

HiWy - AFR

For engine safety, I just wouldn' advise playing with this without a WB O2 telling you what you're actually getting. Especially now that youd intentionally be trying to run lean. I have mine set to run about 16:1 actual AFR.

Re: lean cruise

If you're using an $8D mask, make sure the Force BLM Idle Cell CCP %DC threshold is set to 0.

IIRC, having values greater than 0 can get you stuck in BLM Cell 4 during non-idle operation when the CCP becomes active, and can interfere with getting into Highway Mode.

EDIT: Just saw that you're running the EBL, so this comment may not apply.

This one should be un-set:

Option Word 4 - Bit 0 - OpHwy

Setting it allows highway mode while in open loop.
