Following on from my comment yesterday (08-Dec), it dawns on me that you could achieve a static drain connection to some bearings with adhesive backed shielding tape - the material I referenced earlier.
The adhesive is conductive, and you can solder to the foil.
Depending on the construction of your turntable bearing, you could solder a ground wire to the foil, then peel the backing off and affix it to the bearing.
It might take some fiddling, and obviously won’t work in all situations, but it’s something that might work for you.
I just finished a roll of this, and it works as advertised: https://www.stewmac.com/electronics/shielding/conductive-copper-tape.html
I recently picked up a roll of this, but haven’t used it yet: https://www.amazon.com/gp/product/B07C6YLNYL/ref=ppx_yo_dt_b_asin_title_o01_s00?ie=UTF8&psc=1
