No! Process in phones are not designed for overclocking so don't do any attempts of doing it and it can damage the processor and the phone permanently.
Yes you can but the warranty and knox will be void. If you don't need that and you still want to try it out you just need to get TWRP on your device (plenty of tutorials out there for how to do it) and then you need to flash a custom kernel (specific to you device model) that allow overclocking. For example you can flash this kernel: (XDA [KERNEL][SM-T510] Infinity Kernel 1.2 - ASK1) on the Galaxy tab A 10.1 (2019) SM-T510 and you will get higher clock speed and better performance but it will not be as good as the exynos 9610 because the 7904 has fewer "big cores" (A73).
