Is it okay to drive in the rain without a splash guard?

Is it okay to drive in the rain without a splash guard, it is okay to drive in rain without splash guard short term without immediate engine failure, as car will still run, but not ideal long term as splash guard also called engine under cover protects engine bay from water and mud and debris splashing up from wet roads and puddles, with driving in rain without guard allowing more water to enter engine bay potentially causing moisture on electrical components and more dirt and increasing corrosion risk and slightly reducing aerodynamics. For example, short rain drive without guard okay but replace soon. So it is okay to drive in rain without splash guard for short periods like to get to shop for replacement, but you should avoid driving through deep standing water and should replace guard soon, as prolonged rain driving without guard exposes engine to more water and dirt, with guard helping keep engine bay drier and cleaner, so while not emergency, better to have guard installed for protection especially in wet conditions and to maintain fuel efficiency and reduce noise.
