TLS CBC Ciphers Are Offered on proxmox server... how can i disable that?

I tested the ssl on my proxmox server and i found out that proxmox is using CBC which is considered to be weak. Does anyone know how i can disable that?
I am new to proxmox and after doing some research i found out that i should edit some files in /etc/default/pveproxy or /etc/pve/local/pveproxy-ssl.conf
I didn't find the /etc/default/pveproxy directory on my server and the file pveproxy-ssl.conf also doesn't exist.

This is my scan results:

TLSv1.2

xc028 ECDHE-RSA-AES256-SHA384 ECDH 253 AES 256 TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA384

xc027 ECDHE-RSA-AES128-SHA256 ECDH 253 AES 128 TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA256
