Hi,
In GUI, you can find the BGP under each Leaf (not host) where you have BGP configured:

If you want to see the BGP info from CLI, you can use NX-OS BGP command, directly from leaf CLI.
From ibash:
Leaf101# show bgp ...
Leaf101# show ip bgp ...
Or from NXOS shell:
Leaf101# exit
Leaf101# vsh
Cisco iNX-OS Debug Shell
This shell should only be used for internal commands and exists
for legacy reasons. User should use ibash infrastructure as this
will be deprecated.
Leaf101# show ip bgp ?
A.B.C.D Display one particular network from the BRIB in detail
A.B.C.D/LEN Display one particular prefix from the BRIB in detail
all Display BGP information for all address families
community Display routes matching the BGP communities
community-list Display routes matching the community-list
...
Cheers,
Sergiu
