MACsec (IEEE 802.1ae) adds a security tag to an Ethernet frame and encrypts the IEEE 802.1Q field, the EtherType and the payload field.
If you want to use VLAN, you need the 802.1Q field to announce the VLAN ID. The EtherType is usually set to 0x8100.
However, both MACsec and VLAN use an unique EtherType. As far as I undertand, the security tag introduced by MACsec uses an own EtherType. Is it possible to use MACsec and VLAN in parallel?

Welcome to Network Engineering! There is no standard for MACSec and 802.1Q, so manufacturers have come up with their own solutions. Cisco calls it "WAN MACSec," and does it this way:
The WAN MACsec offering is standards based but offers additional
capabilities not found in earlier MACsec capabilities. More
specifically, MACsec can be leveraged by enterprise customers over
public carrier Ethernet offerings, allowing customers to adapt to the
public carrier Ethernet service offering and capabilities (or
restrictions).
New enhancements for WAN MACsec include:
802.1Q Tag in the Clear
Standard IEEE 802.1X-rev MACsec Key Agreement
Integrated MACsec authentication adaptability over public Carrier Ethernet transport
802.1Q Tag in the Clear
This enhancement offers the ability to expose the 802.1Q tag outside
the encrypted MACsec header. Exposing this field offers a multitude of
design options with MACsec, and in some cases of public Carrier
Ethernet transport providers, is necessary for leveraging certain
transport services (see use case section).
