Review this tutorial video for how to disable or enable AVX support in Windows 11 or 10.

Note that the G15 5520 supports standard AVX and AVX2 instruction sets, but the AVX-512 is not supported.
If enablement AVX in operating system didn't work, you may want to reset hardware configurations back to factory defaults. Remember to take note of your boot settings in BIOS and making adjustments if necessary.

I've also tried that method but it didn't change. After some research I've heard it's possible to re enable avx ,avx2 in bios but dell bios has those settings hidden

To make sure we are on the same page, to perform a Real-Time Clock (RTC) reset on your Dell G15 5520, shut down the laptop completely, plug in the AC adapter, and press and hold the power button for 30 to 35 seconds (until the power LED blinks three times), then release it. That should reset the hardware configuration to factory defaults.
