@Nnylg, Welcome to HP Support Community. 

Thank you for posting your query, I will be glad to help you. 
Yes, you can adjust the CPU speed on your HP Spectre x360 15-df1010na (EB0053dx) to improve performance after the BIOS update. Here are some options to tweak CPU performance:

Check BIOS Settings

• Enter BIOS (Press F10 at startup).
• Look for CPU Performance Mode or Intel SpeedStep and enable it.
• If Intel Turbo Boost is disabled, enable it.

Adjust Power Plan in Windows

• Open Control Panel > Power Options
• Select High Performance or Ultimate Performance (if available).
• Click Change Plan Settings > Change Advanced Power Settings
• Expand Processor Power Management
  • Set Minimum Processor State to 100%
  • Set Maximum Processor State to 100%

Check Intel Throttle or Thermal Limits

The BIOS update may have applied thermal throttling settings to keep temperatures low. You can override some of these limits using:

• ThrottleStop (Allows undervolting and power limit adjustments)
• Intel XTU (Extreme Tuning Utility) (Modify power limits and Turbo Boost settings)

Check CPU Throttling with HWMonitor or HWiNFO

• Install HWiNFO or HWMonitor and check:
  • Current CPU Clock Speed (See if it's underclocked)
  • Power Limit Throttling (PL1/PL2 values)
  • Thermal Throttling

Roll Back to the Previous BIOS (If Necessary)

If the performance drop is significant, rolling back to the previous BIOS may help:

• Download the previous BIOS from HP support website
• Use HP BIOS Recovery Tool to downgrade

I hope this helps. 

Take care and have a good day.
