Hi hayyam
Yes. The SIM card page. Can't you find your VoLTE toggle from both SIM1 and SIM2?
Kindly refer to my SIM card page as below

Settings>System>About Phone>Software information
2. Tap into your SIM1 page for further checking.
3. Please try reset Network: Settings>System>Reset options>Reset Wi-Fi, mobile & Bluetooth
