Query regarding removing code that is not needed for my project

I am wanting to remove all the code from the VESC firmware that I will never need. So I will never use any kind of servo, and so I don't need all the encoder code then??

I will only be using hall sensors or sensorless.

As I'm going through the code and removing everything related to servos and encoders I came across the mc_interface_get_pid_pos_now function in mc_interface.c:

float mc_interface_get_pid_pos_now(void) {
	float ret = 0.0;

	switch (motor_now()->m_conf.motor_type) {
		case MOTOR_TYPE_BLDC:
			ret = encoder_read_deg();
			break;

		case MOTOR_TYPE_FOC:
			ret = mcpwm_foc_get_pid_pos_now();
			break;

		default:
			break;
	}

	ret *= DIR_MULT;
	utils_norm_angle(&ret);

	return ret;
}

This leads to the encoder_read_deg function:

float encoder_read_deg(void) {
	static float angle = 0.0;

	switch (mode) {
	case ENCODER_MODE_ABI:
		angle = ((float)HW_ENC_TIM->CNT * 360.0) / (float)enc_counts;
		break;

	case ENCODER_MODE_AS5047P_SPI:
	case ENCODER_MODE_MT6816_SPI:
	case RESOLVER_MODE_AD2S1205:
	case ENCODER_MODE_TS5700N8501:
		angle = last_enc_angle;
		break;

#ifdef HW_HAS_SIN_COS_ENCODER
	case ENCODER_MODE_SINCOS: {
		float sin = ENCODER_SIN_VOLTS * sin_gain - sin_offset;
		float cos = ENCODER_COS_VOLTS * cos_gain - cos_offset;

		float module = SQ(sin) + SQ(cos);

		if (module > SQ(SINCOS_MAX_AMPLITUDE) )	{
			// signals vector outside of the valid area. Increase error count and discard measurement
			++sincos_signal_above_max_error_cnt;
			UTILS_LP_FAST(sincos_signal_above_max_error_rate, 1.0, 1./SINCOS_SAMPLE_RATE_HZ);
			angle = last_enc_angle;
		}
		else {
			if (module < SQ(SINCOS_MIN_AMPLITUDE)) {
				++sincos_signal_below_min_error_cnt;
				UTILS_LP_FAST(sincos_signal_low_error_rate, 1.0, 1./SINCOS_SAMPLE_RATE_HZ);
				angle = last_enc_angle;
			}
			else {
				UTILS_LP_FAST(sincos_signal_above_max_error_rate, 0.0, 1./SINCOS_SAMPLE_RATE_HZ);
				UTILS_LP_FAST(sincos_signal_low_error_rate, 0.0, 1./SINCOS_SAMPLE_RATE_HZ);

				float angle_tmp = utils_fast_atan2(sin, cos) * 180.0 / M_PI;
				UTILS_LP_FAST(angle, angle_tmp, sincos_filter_constant);
				last_enc_angle = angle;
			}
		}
		break;
	}
#endif

	default:
		break;
	}

	return angle;
}

Is this funtion only used for servo motors? Can I safely remove this function if I am only running a motor with hall sensors or no sensors at all?
