Relay, “Faint” high pitched noise, goes away when clutch depressed

[Spice52]

Hello

just drive a 2018 160hp relay, only 68k miles, drove nice but there was a “Faint” high pitched noise, it’s not loud and goes away when clutch depressed

im wondering if it’s clutch, maybe release bearing noise (not gearbox)

clutch was smooth and light, gearbox felt smooth

Any ideas..?

thanks for info
