Can we integrate the update_critic function and update_cpc function together?

Hi, can we integrate the update_critic function and update_cpc function by adding the critic_loss and cpc_loss together?
Meanwhile, we only need two optimizers.
Is it feasible?

self.cpc_optimizer = torch.optim.Adam([self.CURL.W], lr=encoder_lr)
self.critic_optimizer = torch.optim.Adam(self.critic.parameters(), lr=critic_lr, betas=(critic_beta, 0.999))
loss = critic_loss + cpc_loss
loss.backward()
self.critic_optimizer.step()
self.cpc_optimizer.step()

In other words, I want to incorporate update_cpc into the update_critic function.
Do you have any suggestions, please?
