How to switch off stealthChop mode in library for TMC2209?

Please help me to find way to switch off stealthChop mode for TMC2209.

Driver working in UART mode.

My code initialization part:

 TMCdriver->begin();                                              // UART: Init SW UART (if selected) with default 115200 baudrate
 TMCdriver->toff(5);                                               // off time and driver enable
 TMCdriver->rms_current(_params.CURRENT_);    // Set motor RMS current
 TMCdriver->microsteps(_params.MICROSTEP_);  // Set microsteps
 TMCdriver->shaft(false);                                       // SET DIRECTION
 TMCdriver->en_spreadCycle(false);                      // SpreadCycle™ - highly dynamic motor control chopper
 TMCdriver->pwm_autoscale(true);                       // two modes of PWM regulation, Needed for stealthChop

struct driverParams {
    uint8_t EN_PIN_ = 40;
    uint8_t DRIVER_ADDRESS_ = 0b00;
    float R_SENSE_ = 0.11;  // The current sense resistor
    int CURRENT_ = 2000;
    uint8_t MICROSTEP_ = 2;  // 1/2, 1/4, 1/8, 1/16 - going up - less torque power, more precision
    float MAX_RPS_ = 4;
    float STEP_RPS_ = 0.05;
    int STEP_PAUSE_ = 100;
};
