Static route by ASN

[fathibn]

Hi,
I have twwo internet connections to two different ISPs and would like to direct outgoing traffic to some ASN (mainly facebook, instagram, ...) to go through a given one of them.
I added an alias to the desired destination facebook_Meta_asn_32934_n_63293 and would like to add a static route to that ASN, so non production traffic goes through a given ISP.
Couldn't find how to do it.
Could someone help me please ?
TIA.

Did you try using PBR?

As per my knowledge Static routes do not allow Alias as object for destination.

FW rule with destination of the ASN Alias and pointing to a specific GW?
