How to level uneven floorboard ready for engineered wood floor in herringbone pattern.

Hi I’m laying an engineered oak flooring, iv had to take up the old Lino tiles, & am having to replace the 6mm ply, but the floorboards the ply will be covering are very uneven, there are dips up to 10mm in places. Iv planed down most of the high spots but I need to level out the dips, I was going to do this with a self levelling compound, but am unsure weather to put the levelling compound onto the floor boards, then put down the 6mm ply, or do I put the ply down, then level out the low spots that will still be visible as the ply is so thin & flexible?? Then lay the engineered oak floor onto the ply/levelling compound? The customer has brought adhesive to glue down the floor, but I prefer to nail, my concerns are if I nail into the compound it will break up? Any help or advise will be greatly appreciated. Thanks.
