Replacing Default Logger for Global Effects

Is it possible to globally replace the default logger for any effect run with the default runtime?

I know I can replace it for a given effect

const loggerLayer = EffectLogger.replace(Logger.defaultLogger, JSONStringLogger)
const foo = pipe(myProgram, Effect.provideSomeLayer(loggerLayer))

const loggerLayer = EffectLogger.replace(Logger.defaultLogger, JSONStringLogger)
const foo = pipe(myProgram, Effect.provideSomeLayer(loggerLayer))

But if I can't compose my program into a single effect any other Effects will still use the default

pipe(Effect.log("this still uses the default logger"), Effect.runSync))

pipe(Effect.log("this still uses the default logger"), Effect.runSync))
