Minor but could reduce indentation here:

func (c *ShadeformClient) getEstimatedDeployTime(shadeformInstanceType openapi.InstanceType) *time.Duration {
	bootTime := shadeformInstanceType.BootTime
	if bootTime == nil {
		return nil
	}

	minSec := bootTime.MinBootInSec
	maxSec := bootTime.MaxBootInSec

	var estimatedDeployTime *time.Duration
	if minSec != nil && maxSec != nil { //nolint:gocritic // if else fine
		avg := (*minSec + *maxSec) / 2
		avgDuration := time.Duration(avg) * time.Second
		estimatedDeployTime = &avgDuration
	} else if minSec != nil {
		d := time.Duration(*minSec) * time.Second
		estimatedDeployTime = &d
	} else if maxSec != nil {
		d := time.Duration(*maxSec) * time.Second
		estimatedDeployTime = &d
	}
	return estimatedDeployTime
}
