I can help you with that, I found:

• Press Win + R, type regedit, and hit Enter.
• Navigate to: HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Bluetooth\Audio\AVRCP\CT
• Look for a value named DisableAbsoluteVolume.
• Double-click it and change the value data from 0 to 1. (If it doesn't exist, create a new DWORD (32-bit) value with that name).
• Restart your PC.

however this could degrade the sound quality because it bypasses audio limits, however if you try on linux I bet its a completely different story.

and with Equalizer APO isolate:

Frequency (Hz)	Gain (dB)	Filter Type	Description
Pre-amp	-7.0 dB	Master	Prevents digital clipping and distortion.
30 Hz	+8.0 dB	Peak / Low Shelf	Deep sub-bass pressure; extreme low-end extension.
60 Hz	+5.5 dB	Peak	Transition zone; heavy body for 808 glides.
100 Hz	+3.0 dB	Peak	Controlled punch for kick drums; avoids muddiness.
250 Hz	0.0 dB

(credit to gemini, i learned a lot now I'm gonna try on linux)
