RPM package conflict between remi-safe and mariadb repo

I am running Centos 7 with additional repositories remi-safe and mariaDB-10.5. Everything worked fine for several months, now I get a package conflict when running yum update:

Error: Package: libzip5-1.8.0-2.el7.remi.x86_64 (remi-safe)
Required: libzstd(x86-64) >= 1.3.6
Available: libzstd-1.3.4-1.el7.x86_64 (mariadb-main)
           libzstd(x86-64) = 1.3.4-1.el7
Error: Package: libzip5-1.8.0-2.el7.remi.x86_64 (remi-safe)
Required: libzstd(x86-64) >= 1.3.6
Install: libzstd-1.3.4-1.el7.x86_64 (mariadb-main)
         libzstd(x86-64) = 1.3.4-1.el7

I tried to solve this by setting priorities to the yum repos (I gave 1 to MariaDB, 2 to Remi, 3 to Centos Base packages and 4 to EPEL) but this did not solve the issue.

How could I get remi-safe and mariadb-10.5 to live on the system again without quarreling?

EPEL have zstd 1.5.0, so you must use this one

So should either disable priority plugin or configure it properly, with higher priority for base and EPEL repository, higher priority means lower value.

Notice that mariadb 10.5 is available in official CentOS SCLo repository, which is probably better integrated to system.
