There were only 3 choices based on RFEF criteria (a referee cannot be allocated for 2 games of a given team in the same calendar month):
1) Lahoz
2) Munuera Montero (recently reffed Barca - Mallorca 5:2; Getafe - Madrid 0:3 or in 18/19 Barca - Eibar 2:2 and Madrid - Sociedad 0:2)
3) De Burgos Bengoetxea (Madrid - Levante 3:2; Barca - Villarreal 2:1; Valladolid - Madrid 0:1)
Neither of the others reffed any major Derby as far as I can see. On paper De Burgos only had one hard game, Atleti vs Sevilla in 18/19.
E: Correction, De Burgos did ref a SuperCopa Clasico in 2017/18, the game that ended 1:3 to Madrid at Camp Nou. And Liga Madrid Derby in 16/17 ending 1:1, as well as Valencia - Madrid 2:1 in that same season. He's also a European & international licensed. So I guess he's not so green.
