Domain mail is on Gmail.
It is necessary to make a mailing list from the mail on this domain via Mailchimp.
I prescribe DMARC which is provided to me by Mailchimp, and mail distribution is blocked for some domain mail users. Is it possible to combine dkim from gmail and mailchimp?

dmarc error is not only dkim, but also spf, which you have is not correct! you can not make more than 1 spf entries. When requested, the receiving party will use only one entry. Therefore, remove the superfluous and supplement the working one.
There are dkim entries for both selectors. so let's not touch dkim yet.
You need to look at the headers of the letter to understand what is wrong in it.

You need to do two things:
1. Write the Mailchimp and Gmail SPF policies in SPF include:

2. Create a separate DKIM selector for Mailchimp, generate a DKIM key pair , publish the public key in DNS with this selector, register the private key in Mailchimp for mailings
