First, I don't see any inductors on your board.
Second, I could find no other complaints about noisy GDDR5X boards on the web. Gamers love this board and would be complaining if there's a wide spread issue.
Third, why suggest using a thermal epoxy, when a neutral cure silicone rubber [some would argue 2-part epoxy resin] used for staking components might be more appropriate?
Forth, given the low mass of the components that we're talking about, I wonder if your board is defective in the fashion you propose. [Or something else is the problem with this board or interactios.]
Fifth, maybe the "high pitched noise" is caused by radio frequency interference [RFI} between different elements in your rig? Google => troubleshoot rfi ... for advice.
Bottom line: I don't think staking your "inductors" to the board will alter their performance. Continuing, I don't think it will fix your problem, either.
Bonus comment: I'd talk to a board supplier app engineer before using weapons on my very nice board.
