Can we assume that queries written with clause.Locking are transactional by default?

[Inderdeep01]

As I was reading the docs, I came across this line:

GORM perform write (create/update/delete) operations run inside a transaction to ensure data consistency, you can disable it during initialization if it is not required

Source: https://gorm.io/docs/transactions.html

I am to perform some update operations on the db using the lock clause. I was wondering if I need to take care of the transaction myself or I can assume the before mentioned statement to be true in this case?
Thanks

result := db.DB.Model(Payment{
		TransactionState: TransactionInitiated,
	}).First(Payment{
		Id: orderId,
	}).Clauses(clause.Locking{
		Strength: clause.LockingStrengthUpdate,
	}).Updates(Payment{
		TransactionState: TransactionCompleted,
		Status:           status,
		PaymentMethod:    method,
	})
