This isn't enough to stop the clash so perhaps schematic is for some non-Beta-supporting version or has an error.
Assume for now the entire joystick is disabled as that's the only way Beta can work.
Beta support seems limited to Beta v3/plus (TR-DOS 3/4.xx) models, beta128 (TR-DOS 5.xx) doesn't work.
- Bios rom "mu21e7" has issues with Betaplus, doesn't work with betav3,beta128,betacbi, perhaps it's for some other interface entirely...?

The enable/disable switch became necessary on later versions as games had started including checks to detect presence of the interface.
eg. Renegade ("The Hit Squad" re-release) whilst loading, reads from 0x9f specifically to cause the MF (if present) to page in and crash the machine.
