That shows that your DC knows about the 'nTDSDSA' objectclass and the
'hasMasterNCs' attribute, so why, when you attempt to join another DC
does it say:
objectclass_attrs: attribute 'hasMasterNCs' on entry 'CN=NTDS
Settings,CN=DC6,CN=Servers,CN=Default-First-Site-Name,CN=Sites,CN=Configuration,DC=nicho,DC=com'
does not exist in the specified objectclasses!

20.04 comes with Samba 4.15.13, so where did you get the 4.19.5
packages from ?

Probably not, but what does this command show:
ldbsearch -H /var/lib/samba/private/sam.ldb -P -b
'cn=Schema,cn=Configuration,DC=nicho,DC=com' -s base objectVersion
