Which Grove - I2C Motor Driver you can recommend to connect and control a S30K Electric Brushless Motor, 12 V DC: https://www.aliexpress.com/w/wholesale-S30K-Electric-Brushless-Motor.html so I do not need to use a 5A 90W PWM 12V DC Motor Speed Controller: https://www.aliexpress.com/w/wholesale-Mini-5A-90W-PWM-12V-DC-Motor-Speed-Controller-.html
The S30K Electric Brushless Motor you’re referring to is a brushless DC (BLDC) motor, which cannot be directly controlled using standard DC motor drivers or basic PWM controllers. BLDC motors require a special type of driver that can generate three-phase signals, typically through sensorless or sensored control (often via Hall sensors).

You cannot use any Grove I2C motor driver for this brushless motor. Instead, consider the Hobbywing QuicRun 10BL60 that is microcontroller compatible.
LED Driver Board for Seeed Studio XIAO: 5V/12V NeoPixel & RGB LED Smart Controller take a look at this… it has the power but i dont think the motor controller
