Guys, that’s just what I suggested.
“raise the hood/guard to allow air flow”
A wye with a secondary hood behind the blade guard will absolutely reduce the pressure on the blade guard.
And plus it will help to catch the fugitive dust that gets out of the guard, if any.

Bottom line, you want more flow and less vacuum pressure on the blade guard.
Allowing air to enter the guard will do this.
If the guard is too small to allow proper air flow, even with it raised off the workpiece, then you need to reduce the pressure.
By opening up a wye connection, directly behind the blade guard the pressure will be reduced and the backup hood will use that dilution air flow to still catch air from the area around the operation where the dust is being generated.
