ACS URL via DHCP vendor specific option 43 or 125?

hello there,

is here someone in the forum who can tell me if the vendor specific option 43 or 125 is on the Tik supported when he acts as dhcp-client?
of course i know, that i can request that option but does it overwrite the ACS url already exists in the tr069 section?

thank you for any help!
