While certainly within the purpose and intent of the rule, it's not specifically mentioned as a violation that's deemed worthy of a bench warning, however rulebook language such as "unsporting" and "not limited to" should cover this situation:

4-48: A warning to a head coach/bench personnel for misconduct is an administrative procedure by an official, which is recorded in the scorebook by the scorer and reported to the head coach.
ART. 1 For conduct, such as that described in Rule 10-5, Articles 1 (a, b d, e, f), 2 and 4, the official must warn the head coach unless the offense is judged to be major, in which case a technical foul must be assessed.
NOTE: A warning is not required prior to calling a technical foul.
ART. 2 For the first violation of Rule 10-6-1, the official must warn the head coach unless the offense is judged to be major, in which case a technical foul must be assessed.
NOTE: A warning is not required prior to calling a technical foul.

10-5-2: The head coach is responsible for his/her own conduct and behavior, as well as substitutes, disqualified team members and all other bench personnel. Bench personnel, including the head coach, must not:
ART. 1 Commit an unsporting foul. This includes, but is not limited to, acts or conduct such as:
a. Disrespectfully addressing an official.
b. Attempting to influence an official’s decision.
d. Disrespectfully addressing, baiting or taunting an opponent.
e. Objecting to an official’s decision by rising from the bench or using gestures.
f. Inciting undesirable crowd reactions.
ART. 2 Enter the court unless by permission of an official to attend an injured player.
ART. 4 Stand at the team bench while the clock is running or is stopped, and must remain seated, except:
a. The head coach as in 10-6-1.
b. When a team member is reporting to the scorer’s table.
c. During a charged time-out, as in 5-11, or the intermission between quarters and extra periods.
d. To spontaneously react to an outstanding play by a team member or to acknowledge a replaced player(s), but must immediately return to his/her seat.

10-6-1: The head coach must remain seated on the team bench, except:
a. By state association adoption, the head coach may stand within the designated coaching box described in 1-13-2. The first technical foul charged directly or indirectly to the head coach results in loss of coaching-box privileges and the head coach must remain seated for the remainder of the game, except as stated below in 10-6-1b, c, d and e.
b. The head coach may stand within the coaching box to request a time-out or signal his/her players to request a time-out.
c. The head coach may stand and/or leave the coaching box to confer with personnel at the scorer’s table to request a time-out as in 5-8-4.
d. The head coach may stand within the coaching box to replace or remove a disqualified/injured player or player directed to leave the game.
e. The head coach may stand as in 10-5-4c and 10-5-4d.
NOTE: The head coach may enter the court in the situation where a fight may break out – or has broken out – to prevent the situation from escalating.
